We went to visit Adrienne in Baltimore. There are so many wonderful things to see and do in Baltimore that you need 4 weeks instead of 4 days! We stayed in the Inner Harbor Area, we went to Port Discovery, Hampden (Adrienne's neighborhood), Harborplace, a day trip to Washington DC and we rode many modes of transportation: airplane, metro (subway), MARC train, and taxi. And we did a lot of walking!!
