What a great place for a day off! So much to discover, so much to do. Of course a trip up the Gateway Arch is always advised. The museum and the story of how it was built is awesome. Speaking of museums, all of them are free in St. Louis. There's a tour bus for a trip around town. Anheuser-Busch offers a tour complete with the famous Clydesdale horses. We were lucky with both the Cardinals and Blues in town. Some toured the college campus and some even hopped on a bike to check out the bike path along the river.
