I've been commuting to Northern Virginia from Baltimore on and off for the last few years and this is a spot that has come to the rescue a few times. This is a very quick stop off of I95 and 495 and would be a good one if you're looking for a Maryland Find on a long road trip. The container is a well gaurded, Muggles shouldn't be too much of a problem but keep an eye out for truck traffic. BYOP and enjoy!
