Hey guys – I’m a friend of Nema’s and been following your adventures since the CNN episode. I’m a former Lexingtonian (in fact, I came to a party at your house once!) and now live in Northern Virginia. Knowing you’re hikers you should try the Billy Goat trail while you’re here – it’s on the other side of the Potomac from Great Falls – lots of rock climbing and a nice hike in general. Highly recommended if you get a chance!
