The Saturday my 12 year old map of Arlington let me down at Ballston, and a stranger at a bus stop fixed it | Arlington Va Recommendations - Pinecone Attack
Of course your twelve year old map failed you, that thing probably still thinks the Metro stops at 2am and Ballston is just a parking lot. It's funny how a random stranger at a bus stop knows more about your own neighborhood than an official map does. At this point just ask the guy to draw you a new one by hand, it'd probably last longer.
