Well when you ask him about it explain the type of stand you' re using and inquire as to why he didn' t originally want you using stands. Maybe he doesn' t want his trees harmed. In that case, get a ladder stand that is tied to the tree and won' t harm it. Maybe he doesn' t want to risk having you get it stolen. Or even worse, fall out of the tree. It can never hurt to ask why. Maybe you can help educate him about the safety of stands and he' ll change his mind. If he says no again and explains why, then you don' t have to ask again.
