have you tried working around the edges for any sign of him coming out yet? Look on all the trails, maybe even walking in on the far side a few yards to make sure he didnt come through! If he didnt you can bet he is in there. I would also bet that is his home range. I bet he is on his last leg and going in tomorrow during daylight would be your best bet! Keep on your toes, when you dont, he'll be near be nearby! best of luck!
