You will be at Camden Yards which is 10 blocks from the Inner Harbor. Lots of things to do there. National Aquarium, USS Constellation, Pontoon boat ride, etc.
Careful, the inner harbor has been a haven of suburban scum, possibly "gangs" or wannabe's. They've been going down and starting fights and targeting individuals they can out number. An of duty cop was beat up a few weeks ago, and there has been a stabbing or two.
hmmm. it'll probably only be me and a close friend who i've known since pre-school. we played baseball together for 12 years, so ESPN Zone might be a great idea!! thanks for the heads up about the gang activity.
