RE: What to do if shot deer goes on posted land?
PA must be more relaxed than WV. In WV it is illegal to go onto posted (or fenced) land without permission...period. You can go to the game warder, but he would need permission as well. Besides if you treepass in WV, you are liable to get shot or thrown in jail. If they went to the trouble to post it, they obviously don' t want anyone on there.
It is always good to try to have a gentleman' s agreement with the adjacent land owners. Obtain this permission prior to hunting season. If you don' t know who the owner is, this information can easily be found at your county court house.
Never enter posted land without permission. Not everyone will take treepassing lightly.
