RE: What would you do?
Don't forget part of the reason Landowner's allow people to hunt their properties is to help keep unwanted people off their land. So if you simply do nothing after the landwoner told you to take it down he may find someone next year who will do what he wants. As far aa being a thief for taking it, give me a break!! The thief is the trespeasser who is using the land as his own!!
