If you're in or around Richmond, there's a fairly new (on the 2nd year) weekly meetup event that is pretty decent:
RVA Bikes & Coffee
Every Sunday, starting at 10:00 am
Starbucks side lot 5001 Huguenot Rd, Richmond, VA 23226
(in between the Virginia Eye Institute and Starbucks)
Typically 50-60 bikes, nice mix with a bunch of Ducati. Waffle truck provides food and coffee/hot chocolate usually most Sundays, but Starbucks right there if that suits your fancy.
More info on the Facebook page:
