It's gotten above 60F a few times now and the first thing the kids do is turn on the water. They were busy for a long time in the back yard, but are old enough now that I don't go check on them very often. Guess maybe I should. This is what I found when they called me out to take a picture.
Nearly every body surface that wasn't covered with clothing, was covered with mud. It was probably good I didn't see it earlier. I probably would have stopped them and ruined all their fun. (I'm pretty good at doing that, at least according to little G.)
