Hunt where the deer will be, not where you have seen them.... this seems to be a problem for alot of my buddies. They see a big deer sneak from a field into the woods while spotting one night and they instantly think that buck will do that same thing over and over! They usually spend most of their season's set-ups based on that one sighting and refuse to adjust to the deer. If you scout out a spot because you have seen a big buck in that area and you don't see anything after a few trips, learn to adjust and move around, eventually you will find "that spot" and everything will fall into place!
