Re: hunting squirrels/best results?
If you've got a kid with you, it's really important you find a den tree with active squirrels. Look for knots, holes, and nests. Also look for scraps of acorns and shells below where the perched and fed. If you get a good den tree that has 2-3 in it, you're in for a fun time. First hour and last hour of light will have them out.
As far as sneaking for squirrels you really can't just walk. Gotta go slow and as quietly as possible. Stop frequently and unfocus your eyes in the treetops and ground and any movement will grab your attention. Sneaking for squirrels is a ton of fun when you can pick out the ears of one in a Y that thinks he has you beat. Still...find a den and find a good spot around 25 - 30 yards away and relax. They'll be out.
