Baltimore is a big dusty and s...ing city. It isn't a place to enjoy. Not really. You just see dirty old buildings. Don't take it too strong I haven't spent much time there. I just travelled through.
Favourite spots:
Hereford is a nice suburbian town. A library with internetconnected computers are also available for free. In Hereford you can go playing miniature-golf. The Gunpowder Falls are near and good for hikes and canouing.
What's really great:
I was working on a summer camp called Camp Puh'Tok (www.camppuhtok.com) for nine weeks. It was about a mile away from Hereford in the forest. Hiking along the Gunpowder River was fun.
