We’ve had a several vintage-y rides around the Pacific Northwest in the last few years, many documented in C&V threads, at least five that I can recall this year. The Portland bunch seem to have quite a few, and the Velo Cirque events held roughly twice/year there attract a few of us to make the drive down from Seattle. Bob Freeman, formerly of the late, great Elliott Bay Bicycles in Seattle, leads frequent vintage rides in the Puget Sound region, but he may be more closely linked to the Classic Rendezvous group.
I’ve really enjoyed the friendships that have expanded beyond just web acquaintances through these rides (and the beer drinking that follows!).
