If you didn't see any other commuters today, it's your own fault. It's not about the schwag, it's about getting to ride to work with a group instead of by yourself. That requires that you go to a staging area and wait for a group to leave. I only waited about ten minutes, while stuffing free food into my mouth.
There was a guy in our group who wasn't a bike commuter before today. I think he learned today that he can ride to work.

Actually,
that's what it's about.
