Larry,
Although I'm not a squirrel hunter myself, a guy can hardly shoot a grouse in the SE bluff country without a squirrel getting killed by accident. There's plenty of public land, lots of oak stands, and plenty of grey and decent numbers of fox squirrels.
In a couple weeks grouse will be open and pheasant will be open mid-October. If the squirrel hunting gets slow there's still plenty to do (bowhunting anyone?). I've hunted the Whitewater area a ton, so if you're headed that way I can give you some specifics.
