As far as driving, (we come from same general area if my memory servies me correct -
Phila), I actually dont reccommend it (if you can get to
Phila).... you can get there fairly easily 1 of three ways
Way 1 - Megabus ticket from Phila to Baltimore aka White Marsh Mall(estimate $5), then take taxi (13 miles, roughly $30).
Way 2 (I'd suggest), Amtrak Phila - Baltimore Penn Station ($35), Bus 11 (linear route) ($2 - 20 mins).
