“Join us for a bike ride around the oldest federal monuments, the DC boundary stones: http://www.
As always, the ride will be sponsored by Boundary Stone DC = ride shirts and an awesome after-party at the bar with specials on DC Brau Brewing Company beers! This year, our new partner Phoenix Bikes will be on-hand at the ride start and rest stop(s) for bike safety and maintenance checks.
