Lots of different ways. But it's not easy, which is what you're getting at.
My neighborhood might be a good example though, we have a 15x5 foot area for our sign and that's it, that's the only common owned property, in a neighborhood of 85, 450k+ houses, all on 2+ acres. They could easily give that to someone with the responsibility to keep it up, he'll we have a **** load of $$$ in the bank for no reason at all.
