We drove to Calera to see the Artrain at the Heart of Dixie Railroad Museum. The 4-car museum contains artwork by Native Americans, a couple of working artists, and a tiny gift shop. The art was beautiful and thought-provoking. The only disadvantage to a train-based museum is that it's difficult to get far enough away from a few of the larger pieces. We also enjoyed wandering among the rows of train cars in the yard of the Railroad Museum.
