John - like Eric, I am also located in Fairfax County and will offer you the same to test ride my Silvio. Mine is set up with Campy components.
Eric - hope to see you on the trail someday. If your are into the cherry blossoms, I would recommend taking the Capital Crescent up to the Kenwood (MD) community. The entire neighborhood is a flood of cherry trees, more than you will find at the Tidal Basin and less foot traffic. My wife and I will be out cruising through with our GTT next weekend.
