How much of a pain in the ass is it to park in the city? I'm going to have a car in the area, but would it be easier to park it and get on a train from somewhere outside the city? I'm going to be staying in Charles Town, WV, (not Charleston) if that makes any difference.
A real big pain in the ass. Finding spots on the street will be lucky, at best. Public lots are expensive. It'd be best maybe to drive to a Metro station like Rockville or one of the far North stations, park, take the subway in, and then out. However, it might be worth it to take a train from Frederick. If you do go to Murphy's, it might be worth it to take your car.
