Ballston, VA to Mt. Vernon, VA: 3
Starting from MaryMount University, Ballston, Arlington VA head East on Custis trail until you hit Key Bridge in Rosslyn. Join the Mt. Vernon Trail South. It was a beautiful day and I needed a workout as I got rained in on Saturday. On the way back, though, dark clouds assembled and it poured.Most bikers and hikers took cover under the trees and bridges. A few like me loved the challenged of biking in the rain. It was fun. It was a short downpour, enough to drench the clothes.
