It isn't about what you can get away with, its about what is right. I've never felt bad about doing the right thing.
Reverse the question, what if you were standing on your ground, shot a deer across the fence. Which tag? Paid. I think only deer you kill on your ground, from your ground, qualify as a land owners tag. So if you only have a land owners tag, stay on your side of the fence to both shoot and kill and then don't worry about trying to get away with something.
Oh yeah, I too speed, I'm willing to pay the consequences of my actions for speeding. I'm not willing to pay the possible monetary, loss of hunting previleges or personal ehtics consequences of breaking game laws.
