Similar situation around here Bocajnala. The weather was on the cool side the first two weeks of September, but since squirrel season opened on the 15th it's been summer-like.
Less so today. I went out on public land again. A really nice spot where a woodlot with lots of big oaks is surrounded by corn on 3 sides. Well I only saw 1 squirrel, and he barked at me for a good 5 minutes. Weird angle though, and I was sure if I moved he'd bolt.
In the end it's good that I didn't shoot, because a doe family group walked right in front of me shortly after. 1 adult, 1 yearling, 2 fawns. They didn't smell me, but I bumped the younger 3 on the field edge on the walk out. Hopefully they have short memories because I want to go back next week with my crossbow.
