Highlight of our Christmas trip = St. Louis City Museum

I expect I'll have more to say about this, but the best place I've ever visited with my kids has to be the St. Louis City Museum, which we visited during the Christmas holidays. It's a strange duck, not like much else, but you won't go wrong by thinking of it as a big, mostly-indoor playground built from objects found throughout the city, but including lots of custom sculpture as well, to the point where it's as much a hands-on art museum as anything else. This is something you should not miss if you go through St. Louis at all.
