Moving into serious teritory

I have been scoping out options for the next hanging. East Houston is where it has to happen, I like the idea of putting one up outside wholefoods but the trees are far from ideal. I am pursuing the freegan aspect with the next two trees i plan to hang food from. Tonight if i can deal with the cold i am doing the apple in a rubbish bag tree, then the next one i am excited about. I am going to go recover some edible waste from out side supermarket and hang them. Fruits of the streets of New York City. Wondering if anyone will feel comfortable to pick this tree, think it might feel destructive. Dont want to include a sign but feel i need a way to get my concept across clearly.
