Never had a need to scout for squirrels. I always just went to their food source and looked for them. You didn't say where you're from. But I assume you have some kind of hardwood's around your area. Look for beachnut, walnuts, oak, pecan, any of the trees that bear nuts and you'll find plenty of squirrels. Also keep an eye open for their nests. Another place to check for squirrels is an area of the woods next to crop fields like corn. Always a great spot for tree rats.
