I saw something I would love to try out sometime, and it may work in your situation as well. Pretty sure it wasa Drury movie I saw this in, a corn chute.

Other than that, I sure don't see where else you could put a stand that would benefit you in any way. But then again, you know the "expert" that I am....[&:][&o]
