I went last month and it was great, maybe 70-100 bikes of all types. True vintage British and Japanese plus BMW from 1960 and that's just what I noticed. Also I had a great breakfast for $12.
Look them up on the net...bikesandbreakfast
It's in Clifton, VA
I arrived at 0800 last time and there were more than a few bikes, by 0930 it was packed. Over by 1100.
See ya there
