RE: experienced opinion needed please
make sure your careful with your scent and don't leave to many clues that you've been in the area if possible. like the other guys said, those bucks probably went nocturnal. but be patient and u may get a crack at one. sounds like a nice spot. it will stay that way as long as it's not over hunted, ie lots of human oder and activity around your spot. try some antler rattles or scent, it may be what u need to bring out the big boys. good luck bro.
