Boy it was really expensive, but we had a good time at the Museum of Science. On one hand, the exhibit that drew us there, All Aboard! Trains at Science Park, was flimsy. On the other, it still captivated the guy.
A lot more of the museum connected with him than before, of course, but it's not like we've hit Peak Age Range like we have with the Children's Museum. I think it'll be another four years or so.
