He was playing with it even before his ankle/leg healed... and when we moved it off the cement and into the yard, I think he appreciated the change. :)
It has a door, window shutters, a slide, and even a "key" that he can turn. What more could a kid ask for? Besides another kid to share it with, I mean... but I suppose that'll have to wait, at least until next year (at the earliest!).
