Moderately hilly to hilly.  Here’s a challenging ride through the southeast Fairfax County suburbs with some rural roads.  Take a spin and judge for yourself.  Part of the latter half of the route goes past the old Lorton Penitentiary.  Meet at first entrance to school parking lot.  Lunch afterwards at a nearby eatery. Call in the event of questionable weather.  Check the web site for cancellation information or call an hour before the ride start.  For detailed directions, do an internet map search for Gunston Elementary School, Lorton, VA.
