Board of Directors
VeraSun Energy Corporation
100 22nd Avenue
Brookings, SD 57006

Dear Directors:

We have acted as special South Dakota counsel to VeraSun Energy Corporation, a
South Dakota corporation (the "Company") and VeraSun Aurora Corporation, a South
Dakota corporation (the "South Dakota Guarantor") in connection with certain
South Dakota corporate issues subsidiary to, but not including, the registration
by the Company under the Securities Act of 1933 (the "Act") of $210,000,000
aggregate principal amount of 9 7/8% Senior Secured Notes due 2012 (the "Notes")
and the registration of the Guarantees endorsed on the Notes by certain
guarantors including the South Dakota Guarantor (the "Guarantees"), all of which
were issued under an Indenture, dated as of December 21, 2005, as supplemented
on May 4, 2006 (the "Indenture"), between the Company, the Subsidiary
Guarantors, and Wells Fargo Bank, N.A., as Trustee. We have reviewed the
corporate actions of the Company in connection with this matter and have
examined the Registration Statement filed by the Company under the Act with the
Securities and Exchange Commission on June 22, 2006 (the "Registration
Statement"), those documents, corporate records, certificates of the South
Dakota Secretary of State, and other instruments we deem necessary for purposes
of this opinion.





Based on the foregoing, it is our opinion that:

     1.   Each of the Company and the South Dakota Guarantor has been duly
incorporated, is validly existing as a corporation in good standing under the
laws of the State of South Dakota, and has the corporate power and authority to
carry on its business as described in the Registration Statement and to own,
lease and operate its properties as described therein.

     2.   The Notes and Guarantees have been duly authorized by all necessary
corporate action of the Company and the South Dakota Guarantor, to the extent
party thereto.

This opinion is based solely upon the general corporate laws of South Dakota,
excluding any securities or blue sky laws. While this opinion is directed to
you, we also authorize Stoel Rives LLP to rely hereon for its opinion in
connection with the Registration Statement.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

Sincerely,

/s/ Cadwell Sanford Deibert & Garry LLP
