If you go to St. Louis, make sure to visit the City Museum (http://www.citymuseum.org/). It is an incredible, unique playground to explore for children and adults alike. It is hard to explain what it is and explanations don't do it justice. To this day it is our fondest memory from the trip to St. Louis.

Bring knee pads!

And take off any fancy shoes before going down a slide! (Or even better, don't wear fancy shoes.) My wife's shoes got ruined by friction in the heel area. Still glad we went, it's an awesome place. :)

You can even pair it with a visit to the Strangeloop tech conference (http://www.thestrangeloop.com).
