i've been there, last time was year before last. it is a bit of a drive from northern Va; have to go to baltimore beltway (695) then up 83 toward York PA for a couple of miles. last time i went, it was a little bigger than the recent potomac swap meet at DIM in herndon. but heck, any swap meet is a good reason to get out in the P-car! i'm always on the lookout for rusty used junk to fill the void in the basement
