I wish I had room to do that. I've been thinking of putting some of the small ones around the fish tail palm and see if it will grow up it a bit and then fall back - inside my yard. I've noticed that the one that has reached the top of the wall sent a long branch out into space and then presumably fell back on the neighbors side. However, at the top of the wall there are 2 new branche starting and I'm hoping they will come towards me (and the sun).
