I totally agree with Robbie as well as some of the others.. You need to get the law involved.. The Game Warden will check it out at least once, then each occurance you report will be on file.. Sometimes, if they are somewhat "slow" and dont have many cases to follow, they will concentrate on a recent report to nip it in the bud.. Best way to go IMO.. The posted signs are manditory, patroling your land(you or other trusted hunters) is manditory, and your not overreacting, its a safety issue.. I'm a hunter and I completely agree with you being nervous..
As for the apple, its a hunter, no doubt(IMO).. Surely at least a tresspasser... I have, myself (whether completely right or wrong) after eating an apple in the stand, tossed the core in the woods near my stand.. I figure its not really bait and I'm not keen on packing something quickly biodegradeable (like a messy food) out of the woods.. Deer definitly like apples in this area, so it probably doesnt hurt to have the scent arround you, but one apple isnt bait in my mind.. The point I'm getting to, and the scary part is he may have been watching you from his stand when you found the apple if it was that fresh
.. Next time youre in the area, look at the trees.. Look for a >8-10" diameter tree with a straight trunk and no branches up to about 30'.. Look at the tree and see if the bark is scarred. A climber(most likely what he used) will leave marks on the tree, usually faint, but still marks..
