They do a swap meet a couple of times a year, I believe.
I missed the last one.
I won't miss the next.
(Famous last words!)
But yeah, Joe sells donated, unwanted (historically speaking) bikes out front (he also posts them on Craigslist pretty often), and they get donations all of the time, which they often sell bits from in order to keep the lights on over there.
It's an excellent establishment run by total legends and friendly volunteers.
Fantastic thread, and despicable that I have not yet been to the museum, since I live and grew up in the Santa Cruz mountains, birthplace of so many legendary builders and trails. Which brings me to think that if any of you happen to be in the greater Bay Area at any point that maybe I could try to get us a tour with Rock Lobster and to secondarily show you some of the great single track that must have inspired Keith, Brent, Paul, and others. There seems to be such a larger and more enthusiastic group on retrobike than in the US, and it's a shame the mecca is so far away. But happy to share anything I know about the local trails and lore ( not that it is that much, mind you....). Cheers, all!
