         Re: Registration Statement on Form S-4 relating to 4.20% Senior Notes
due 2009 and 5.40% Senior Notes due 2014

Ladies and Gentlemen:

                  Reference is made to the Registration Statement on Form S-4
(the "Registration Statement") filed by International Speedway Corporation, a
Florida corporation (the "Company"), with the United States Securities and
Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Act"), relating to the registration under the Act of $150,000,000
aggregate principal amount of 4.20% Senior Notes due 2009 and $150,000,000
aggregate principal amount of 5.40% Senior Notes due 2014 (the "Registered
Notes") to be offered by the Company in exchange (the "Exchange Offer") for a
like principal amount of its issued and outstanding 4.20% Senior Notes due 2009
and 5.40% Senior Notes due 2014, as applicable (the "Outstanding Notes"). As set
forth in the Registration Statement, we are passing upon certain legal matters
for the Company in connection with the Exchange Offer. The Registered Notes are
to be issued under separate Indentures, each dated as of April 23, 2004, between
the Company and Wachovia Bank, National Association, as trustee (collectively
the "Indentures"). At your request, this opinion is being furnished to you for
filing as Exhibit 5.1 to the Registration Statement.

                  In our capacity as counsel to the Company in connection with
the Exchange Offer, we have examined each of (i) the Company's Amended and
Restated Articles of Incorporation, Articles of Amendment to Amended Articles of
Incorporation, and Amended and Restated By-laws, each as amended to date; (ii)
the Indentures; and (iii) the originals, or copies certified or otherwise
identified, of corporate records of the Company, including minute books of the
Company and certain of its subsidiaries as furnished to us by the Company,
certificates of public officials and of representatives of the Company and
certain of its subsidiaries, statutes and other instruments and documents as a
basis for the opinions hereinafter expressed. In giving such opinions, we have
relied upon certain certificates of officers of the Company with respect to the
accuracy of the material factual matters contained in such certificates. We have
assumed that all signatures on documents examined by us are genuine, all
documents submitted to us are authentic and all documents submitted as certified
or photostatic copies conform to the originals

thereof. Further, we assume that the Exchange Offer will be consummated as
described in the Registration Statement.

                  On the basis of the foregoing, and subject to the assumptions,
limitations and qualifications set forth herein, we are of the opinion that:

                  1.       When (i) the Registration Statement has become
effective under the Act and (ii) the Registered Notes have been duly executed,
authenticated and delivered in accordance with the provisions of the Indentures
and issued in exchange for Outstanding Notes pursuant to, and in accordance with
the terms of, the Exchange Offer as contemplated in the Registration Statement,
the Indentures will have been duly authorized, executed and delivered by the
Company and the Registered Notes will constitute legal, valid and binding
obligations of the Company enforceable against the Company in accordance with
their terms, except as the same may be limited by bankruptcy, fraudulent
conveyance, insolvency, reorganization, moratorium or other laws of general
applicability relating to or affecting the enforcement of creditors' rights and
to general principles of equity and public policy (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

                  2.       The discussion in the Registration Statement under
the heading "Material United States Federal Income Tax Consequences" insofar as
it relates to statements of United States law or legal conclusions, is accurate
in all material respects.

                  The opinions set forth above are limited in all respects to
the laws of the State of New York and applicable federal laws of the United
States, each as in effect on the date hereof. This opinion speaks as of the date
hereof, and we disclaim any obligation to update this opinion.

                  We hereby consent to the filing of this opinion of counsel as
Exhibit 5.1 to the Registration Statement and to the reference to our firm under
the heading "Legal Matters" in the prospectus forming a part of the Registration
Statement. In giving this consent, we do not hereby admit that we are in the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission thereunder.

                                           Very truly yours,



                                           BAKER BOTTS L.L.P.
