I've uploaded a group of pictures to flickr for your enjoyment. The museum was really nice and I think the boys would like it again at some point. I forgot to add that part of the experience was a real train ride on the first mile of commercial railroad build in the United States. It was aboard a retired MARC (Maryland Area Rapid Commute) train and the boys enjoyed that. It really didn't go very fast but they just like being on trains. Linda and Gil are in town this week and the boys are loving the attention per usual. They get more Grandparents later this month with Carolyn and Marsh visit. They should be good and spoiled by then.
