Example

The Example is intended to help you compare the cost of investing in the fund
with the cost of investing in other mutual funds. The Example assumes that you
invest $10,000 in the fund for the time periods indicated and then redeem all
of your shares at the end of those periods. The Example also assumes that your
investment has a 5% return each year and that the fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

Expense Example Dreyfus Minnesota Fund (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years	Expense Example, With Redemption, 5 Years	Expense Example, With Redemption, 10 Years
Class A	544	742	957	1,575
Class B	559	793	1,050	1,548
Class C	275	542	933	2,030

You would pay the following expenses if you did not redeem your shares:

Expense Example, No Redemption Dreyfus Minnesota Fund (USD $)	Expense Example, No Redemption, 1 Year	Expense Example, No Redemption, 3 Years	Expense Example, No Redemption, 5 Years	Expense Example, No Redemption, 10 Years
Class A	544	742	957	1,575
Class B	159	493	850	1,548
Class C	175	542	933	2,030

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover may
indicate higher transaction costs and may result in higher taxes when fund
shares are held in a taxable account. These costs, which are not reflected
in annual fund operating expenses or in the example, affect the fund's
performance. During the most recent fiscal year, the fund's portfolio
turnover rate was 15.17% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund normally invests substantially all of its assets in
municipal bonds that provide income exempt from federal and Minnesota income
taxes. The fund invests primarily in municipal bonds rated investment grade
(Baa/BBB or higher) or the unrated equivalent as determined by The Dreyfus
Corporation. For additional yield, the fund may invest up to 30% of its assets
in municipal bonds rated below investment grade ("high yield" or "junk" bonds)
or the unrated equivalent as determined by The Dreyfus Corporation. The
dollar-weighted average maturity of the fund's portfolio normally exceeds ten
years, but the fund may invest without regard to maturity. Dollar-weighted
average maturity is an average of the stated maturities of the securities held
by the fund, based on their dollar-weighted proportions in the fund.

The portfolio managers focus on identifying undervalued sectors and securities
and select municipal bonds by (i) using fundamental credit analysis to estimate
the relative value and attractiveness of various sectors and securities and to
exploit pricing inefficiencies in the municipal bond market, and (ii) actively
trading among various sectors based on their apparent relative values. The fund
may buy securities that pay interest at rates that float inversely with changes
in prevailing interest rates (inverse floaters) in an effort to increase
returns, to manage interest rate risk or as part of a hedging strategy.

Principal Risks

An investment in the fund is not a bank deposit. It is not insured or guaranteed
by the Federal Deposit Insurance Corporation (FDIC) or any other government
agency. It is not a complete investment program. The fund's share price
fluctuates, sometimes dramatically, which means you could lose money.

   º Municipal bond market risk. The amount of public information available
     about municipal bonds is generally less than that for corporate equities or
     bonds. Special factors, such as legislative changes, and state and local
     economic and business developments, may adversely affect the yield and/or
     value of the fund's investments in municipal bonds. Other factors include
     the general conditions of the municipal bond market, the size of the
     particular offering, the maturity of the obligation and the rating of the
     issue. Changes in economic, business or political conditions relating to a
     particular municipal project, municipality, or state in which the fund
     invests may have an impact on the funds share price.

   º Interest rate risk. Prices of municipal bonds tend to move inversely with
     changes in interest rates. Typically, a rise in rates will adversely affect
     bond prices and, accordingly, the fund's share price. The longer the
     effective maturity and duration of the fund's portfolio, the more the
     fund's share price is likely to react to interest rates.

   º Credit risk. Failure of an issuer to make timely interest or principal
     payments, or a decline or perception of a decline in the credit quality of
     a municipal bond, can cause the bond's price to fall, potentially lowering
     the fund's share price. The lower a bond's credit rating, the greater the
     chance - in the rating agency's opinion - that the bond issuer will default
     or fail to meet its payment obligations. To the extent the fund invests in
     high yield ("junk") bonds, its portfolio is subject to heightened credit
     risk.

   º Liquidity risk. When there is little or no active trading market for
     specific types of securities, it can become more difficult to sell the
     securities at or near their perceived value. In such a market, the value of
     such securities and the fund's share price may fall dramatically, even
     during periods of declining interest rates. The secondary market for
     certain municipal bonds tends to be less well developed or liquid than many
     other securities markets, which may adversely affect the fund's ability to
     sell such municipal bonds at attractive prices.

   º Inverse floating rate securities risk. The interest payment received on
     inverse floating rate securities generally will decrease when short-term
     interest rates increase. Inverse floaters are derivatives that involve
     leverage and could magnify the fund's gains or losses.

   º State-specific risk. The fund is subject to the risk that the relevant
     state's economy, and the revenues underlying its municipal bonds, may
     decline. Investing primarily in a single state makes the fund more
     sensitive to risks specific to the state and may magnify other risks.

   º Non-diversification risk. The fund is non-diversified, meaning that a
     relatively high percentage of the fund's assets may be invested in a
     limited number of issuers. Therefore, the fund's performance may be more
     vulnerable to changes in the market value of a single issuer or group of
     issuers and more susceptible to risks associated with a single economic,
     political or regulatory occurrence than a diversified fund.

Performance

The following bar chart and table provide some indication of the risks of
investing in the fund. The table compares the average annual total returns
of the fund's shares to those of a broad measure of market performance.
The fund's past performance (before and after taxes) is no guarantee of
future results. More recent performance information may be available at
www.dreyfus.com.

The bar chart shows changes in the performance of the fund's Class A shares
from year to year. Sales charges, if any, are not reflected in the bar
chart, and if those charges were included, returns would have been less
than those shown.

Year-by-Year Total Returns as of 12/31 each year (%)

Best Quarter
Q1, 2009:  6.96%
Worst Quarter
Q4, 2010:  -4.02%

The year to date total return of the fund's Class A shares as of 6/30/11 was
3.84%.

After-tax performance is shown only for Class A shares. After tax performance of
the fund's other share classes will vary. After-tax returns are calculated using
the historical highest individual federal marginal tax rates, and do not reflect
the impact of state and local taxes. Actual after-tax returns depend on the
investor's tax situation and may differ from those shown, and the after tax
returns shown are not relevant to investors who hold their shares through
tax-deferred arrangements such as 401(k) plans or individual retirement
accounts.
