It snowed overnight and we brought the thermals back out. A later train departure so Mandy and I walked around Phillie in the snow and spent a short time at the library on the Internet. The train was delayed by snow, so we arrived at Baltimore airport station late. We took a transfer to the airport, and rang the hotel shuttle to get us. After checking in we went by the light rail to Baltimore and looked at Camden Yards -- the home of the Orioles, Babe Ruth's house and the inner harbour. Had tea at the Hard Rock Cafe where there was a mass sing-along of over 200 people to YMCA and Grease. Walked home from the train in the dark.
