Sleeping In A Hole

So Jon has been playing outside a lot lately, even after dark since the time change. He usually brings a "lantern" (flashlight) to light his way. There's a large hole, near the driveway, that he's been diligently digging. You get the picture. Anyway, the other evening I went outside to check on him around 6:30 and I couldn't find him. I called for him and he didn't answer. I put on my shoes and walked around the yard looking for him. I found him laying down in his hole "taking a little nap." According to him, that is. What a little freak!
