I am planning our trip to St. Louis (I was born and raised there, living in Texas now) I have the Zoo, the Science Center, and the Missouri History Museum on the list for field trips while we are there. (have to take advantage to the free stuff right? LOL) I am thinking a trip to the art museum as well, but I don't think my kids will really get into that. Anyone from the St. Louis area have any free/cheap ideas for field trips while we are there? We will be there for 2 weeks at the beginning of April if that helps with ideas. Thanks for any ideas!
