Depredation tags are WORK for the most part! Summertime aint my idea of great weather and snakes, wasps and spiders are EVERYWHERE in treestands and shooting houses. Sure you will get a chance to see what is there, but anything they are doing right now is in no way indicative of what they will be doing in Oct/Nov.

About the first and last hour of light is the only time I would bother with it. It's simply to hot and humid to bother otherwise. Are you limited too shotguns and muzzleloaders? If not I wouldn't bother with a stand, I would stay on the ground and slink around and pop em from the ground!
