My old friends Jason and August (who has more walking endurance than most other pregnant women) came to visit me over the 4th of July weekend. They are from Western Pennsylvania; where my family is from. Reed works on railroad car components. One of the things he wanted to scratch off his "To Do" list first--ride the subway. He said his company has shipped parts to our very own Metro Rail in the past. And what did we do at the Smithsonian--looked at old railroad stuff. Reed said, "I'm going to go back to work (at the rail facility) on Tuesday and when they ask me what I did in Washington I'll say, 'Looked at rail cars!'" He also noticed that Washington had a lot of Subways. No. Not the Metro. The sandwich shops.
