Distance of course, will be the main issue here, as it will mean increased transportation expenses.
But, I saw a semi-derelict UH-1B IIRC, at the Wilson, NC airport, on the National Guard's grounds. I spoke (this was many years ago) with one of the NCNG officers, who told me that they wanted to get rid of the helicopter, and in jest, offered it to me, if I could remove it from their installations.
Also, Easterwood Field, near College Station TX, had a number (6 or

UH-1Hs abandoned in a field within the airport boundaries.
Good luck!
