Good luck!
When I was a youngster, we had a good mixture. But now, it's almost exclusively cat squirrels. It's been several years since I killed a fox squirrel. For the last 2-3 years at a spot that I deer hunt, there was a pair of fox squirrels that I would see almost every time I hunted there. I have squirrel hunted in that area, but was careful not to shoot one of them.
