I just happened to wake up early this morning, and when I looked out the front window, my buddy was there! It's been 1 day short of 3 weeks since his last visit. The time before that was 1 day short of 4 weeks! I went over to him and he was busy trying to burrow himself into a chipmunk hole. He was acting like the whole outdoors is new and a big novelty. I think now that he is either let out once a month or so, or naybe gets out. But I don't think he's outside very often, and seems to head back to wherever he lives shortly after visiting. This time I spent all the time with him until he left, instead of walking away and finding him gone later. He just charged around periodically, came running over to me to play, used my lawn as a litter box, and then eventually just headed through the woods towards the houses to the south. Here he is : https://www.youtube.com/watch?v=ph8NZbvN0IY
