You can pop over to Missouri and hunt them for free on the Mark Twain National Forest. I don't want you to get the impression that it will be an easy hunt. They are not behind every tree. I have killed 2 and probably spent 150 - 200 hours hunting them total. I can show you where to start after that take lots of water, a GPS and have a blast. If nothing else you will have a great walk in the woods and squirrel season opens this weekend! All you will need is a regular hunting license, no special tags.
