I'm a lifelong Fairfax County resident but I love day tripping around here. There's so much to see and do that sometimes I don't know where to start. I recently discovered this link ( http://www.fxva.com/fxva/vacation-pas... ) to a vacation planning tool for Fairfax County. It's pretty cool and very easy to use (and FREE!) and helps figure out what you want to see and do.  Check it out!
