I just got back as well. What a great ride-- sure most of it was relaxed, but I stretched it out a bit towards the Verazano. I didn't keep count, but I talked to a guy with a Mu SL (he likes it), and saw a Brompton, a Dahon Jack and pretty much the rest of their lineup, as well as a few BFs.
Me, I was one of the thousands of guys on a 20 year old road bike.
