If the weather stays fairly mild (which it has in the past), you can ride all they way into December up here.In any case, I think we still got a good 2 months before riding season ends? I'm also a new resident to Virginia, by the way.
Also, if you're looking for some meet-up spots, you can try Common Ground in Middleburg or Orlean Market in Marshall.
If many of you aren't aware, the Triumph dealership in Dulles - Motorcycles of Dulles - does a monthly ride. 4th Sunday of every month. Meet there around 8:30,
then head out for a nice ride in the surrounding area. Just give the shop a call and ask.
Another don't forget: Bikes and Breakfast VA in Clifton, second Sunday of the month. Note - get there early if you want a decent parking place!
