You are in my neck of the woods more or less. Wherever you try to go traffic will likely be a disaster. The DC beltway has constantly bad traffic, like worse than Los Angeles
There is a session in Alexandria, across the bridge form national harbor, but most likely the regular players will be at at the local Comhaltas MAD week, which starts the afternoon of the 15th. You might look at the link
http://www.ccepotomac.org/MADWeek/cce-madweekhome.htmlI’ll be there. I’ve never done it before and have no idea what to expect, but they do list sessions
National harbor is at roughly six am on the beltway circle. MAD Week is at roughly noon. It’d be roughly half an hour traffic willing.
People sometimes say “oh there’s a session near you, ten miles away” and I think yeah but it’s off the beltway and across the legion bridge and at rush hour it’d be faster to walk!
