The way I see it hunting the property line is probably where they are seeing deer. As far as shooting over the fence, well, that's a gray area. Deer do not belong to anyone and put yourself in the similar situation. A huge buck is just over the fence on another property. He is broadside 20 yards away what would you do? Let's all be honest with ourselves. I am betting 99% of us are going to let the arrow fly. It's a tough call but you may be able to work something out that would help everyone involved out.
