since the guy was hunting from a portable, you might want to also question yourself.
Did he have a permit? you had an opportunity to ask him.
was he hunting there with a portable BEFORE you had hung your stand ??
and possibly you had infringed on an area he had also found and done his homework on , maybe even hunted previous years ??
Had he possibly hunted there alot on days you were not there ??
also sounds like he had got in there earlier than you had so if anything after seeing his truck you might have thought about not walking in later and possibly ruining his hunt ??
no he didnt before i put the stand up i made sure there was nobody in that area.. i walked all over to double check.. he was not there all year.. why is everbody making me the bad guy
