wow, nice job.
Got four of these built now. As I thought, my kids wanted a go, so I let them build one each - although my son chose the GE - grr. It also got him into the mood for some mini building, so he went off upstairs and built a little while house with a picket fence - looks kind of like a church, and a fountain, both of which clip into the street scene.
Unfortunately, my plan for these to satisfy my modular curiosity may have backfired. As much as I enjoy them, I think they make me want the full sets even more than before!
