Ladies and Gentlemen:

                  We have acted as counsel to Six Flags, Inc., a Delaware
corporation (the "Company"), in connection with the preparation and filing with
the Securities and Exchange Commission of the Company's Registration Statement
on Form S-4, Registration No. 333-87646 (as amended, the "Registration
Statement"), under the Securities Act of 1933, as amended, relating to
$480,000,000 aggregate principal amount of the Company's 8-7/8% Senior Notes due
2010 (the "Notes").

                  In so acting, we have examined originals or copies (certified
or otherwise identified to our satisfaction) of the Registration Statement, the
Indenture dated as of February 11, 2002, between the Company and The Bank of New
York, as trustee (the "Trustee"), pursuant to which the Notes will be issued
(the "Indenture"), the form of the Notes attached as an exhibit to the
Indenture, and such corporate records, agreements, documents and other
instruments, and such certificates or comparable documents of public officials
and of officers and representatives of the Company, and have made such inquiries
of such officers and representatives, as we have deemed relevant and necessary
as a basis for the opinion hereinafter set forth.

                  In such examination, we have assumed the genuineness of all
signatures, the legal capacity of natural persons, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified, conformed or photostatic copies and
the authenticity of the originals of such latter documents. As to all questions
of fact material to this opinion that have not been independently established,
we have relied upon certificates or comparable documents of officers and
representatives of the Company.

                  Based on the foregoing, and subject to the qualifications
stated herein, we are of the opinion that:

                  The Notes are duly authorized, and, when duly executed on
behalf of the Company, authenticated by the Trustee and delivered in accordance
with the terms of the Indenture and as contemplated by the Registration
Statement, will constitute legal, valid and binding obligations of the Company,
enforceable against it in accordance with their terms, subject to applicable
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
similar laws affecting creditors' rights and remedies generally, and subject, as
to enforceability, to general principles of equity, including principals of
commercial reasonableness, good faith and fair dealing (regardless of whether
enforcement is sought in a proceeding at law or in equity) and except that the
waiver contained in Section 4.06 of the Indenture may be deemed unenforceable.

                  We consent to the use of this letter as an exhibit to the
Registration Statement and to any and all references to our firm in the
prospectus which is a part of the Registration Statement.


                                            Very truly yours,


                                            /s/ Weil, Gotshal & Manges LLP
