Brittany, have you looked into Events and Adventures??? Not sure if its only VA or if MD is part of the area that Events and Adventures caters to. It's basically a singles thing. You sign up and they have a calendar full of events depending on your interests that you can attend. When I was looking into it years ago they had equestrian events, dog lovers events, wine tasting, bowling, rock climbing... Basically a ton of different hobby type stuff and there's no pressure that you HAVE to meet someone if you go, but its a great way to get to know guys with some similar interests.
