thats exactly what I do works great, or if you want to get really technical a fm radio makes a great squirrel call Ive used that trick a few times and works good too lol the best of both worlds listening to the ball game and squirrel hunting at the same time. See a squirrel is a curious animal and you can use its curiousity against it and foreign sounds in the woods will get a squirrels attention and you can trust the squirrel to come and investigate. If you ever noticed why it seems sometimes the squirrels are watching you while deer hunting is because they are they are investigating to figure out what you are or what you are doing. squirrel hunting is so simple thats why it is great for getting kids started in hunting, why make something so easy into something difficult?
