If you are limited to a few spots then be careful to not leave to much scent in those areas as has been said. Some controlled use of cover scents as you exit may help to mask your own. Last year I hunted 3 spots in my two areas to hunt and had good success alternating them every couple of hunts. If I had been ready and had hit the deer that passed through I would still have a lot of meat in the freezer. If your not geting busted and you have good movement in your spots I would be in them consistantly saving the best spot for your Buck and prefered weapon that you hope to take him with. This is what my Nephew taught me and he is a very successful hunter of 12 years now,his wall is full of deer mounts. The bottom line is a good spot will be productive sooner or later. Good Hunting
