I wound up going out, shortly after posting actually. I hit submit, and thought "Well, that's really a dumb reason not to go out." So I put on my spandex and left. I did get some "oh, you have a bike too" nods. Also a "nice jersey" comment and a brief conversation about the bike. Turns out it was an LBS employee from the shop where I got my bike who was volunteering. Apparently he has eagle eyes and noticed the sticker from the shop on my frame.
I had a nice 5-mi ride apart from an patch of badly-paved road and the bike decided she wanted to go somewhere that I wasn't expecting.

Kathi--The start point is a mile away, so we're actually the "get everyone in one place" spot for the non-local riders.
