I have to agree with chucker34. I'd try not to put myself in that position. Fortunately, everywhere I'm lined up to hunt I don't have that problem. If I think it's important to know the adjacent land-owners stance before the hunt. If he refused to let me access his land to track a deer, then I'd put some distance between myself and his property line.
That being said, I'd answer your question with a "maybe". If I tracked a deer to the property line and saw it lying 20 yards on the other side???? I'm probably crossing the line. Sorry.[&o]

GMMAT,
What would you do?
(Had to edit that. I'm not sure what I'd do in that instance, but it would beextremely difficultto leave a buck lying 10-20 yards away because someone doesn't want my footprints on his ground.)
