Love the blog, Leah! I had a great time listening to the pre-trip planning and the wrap-up report (even if you're Cubs fans.)
We got to see the Art of the Brick exhibit at the Magic House in St. Louis last fall. It was really cool. Here's a link about the exhibit if anyone's interested. http://brickartist.com
I think Pete should send you on more family adventures. You do a great job of asking the types of questions that are really helpful for others who are planning. Thanks!
