Favorite thing: One of the main entrances to the University of Maryland campus is where Paint Branch Parkway intersects Baltimore Avenue (US Hwy-1). The campus is quite large and is a nice mix of old and modern, rural and urban. Parking is definitely an issue. I saw only metered or paid parking for visitors (marked with a big green and white "P"). All other parking lots require a sticker. Here is an interactive parking map. The pedestrian crosswalks are strictly enforced, so be ready to stop often.
Favorite thing: Our symposium was held in the new Samuel Riggs IV Alumni Center. It is a very nice facility close to Byrd Stadium and the Dessie M. Moxley Gardens. There is a visitors' paid parking garage next to it. The Hall of Fame inside the Alumni Center is interesting with some names that most everyone would recognize, like Connie Chung and Jim Henson.
