He stayed up the tree for at least 2 hours; from about 9:30 AM 'til 11:30 AM or so. For a couple of the classes it was a fun surprise, but the older ones had caught on by the time their turn came.
Here's another shot of one of the classes in their camouflage. Note the mascot, Cooper the dog, in the middle of the kids. The particular girl, aged 12, who volunteered to be Cooper said; "Never again!" Ha. She had to pose for a shot with every child there; some 50 or so over the course of the week. I guess she got tired of that pretty quick.
Anyway, we had a good time. Sunday will be the big program, where the kids will do their songs and skits and whatever else they've worked on all week. They will also get their crafts and a treat from the teachers.
