I believe this guy probably was in the wrong. Just saying, I have squirrel hunted out of a treestand many times. I realized how many squirrels I would see while deer hunting and how few I saw while sitting on the ground squirrel hunting. Figured it wouldn't hurt to try a treestand. Killed limits.
I've considered doing that. Always noticed more while in my climber compared to sitting on the ground. I've noticed squirrels can notice a hawk flying low or a bobcat and alert all the others. Even sitting on the ground deer hunting I don't notice as many squirrels. Guess it could be due to being able to see more elevated. Always wanted to try it.
