gbcb, that reminds me of the old joke about the personals ad for a woman "for companionship, possibly more, must have own pickup truck. Please send picture of pickup truck."

There are not a great percentage of bike commuters around here, but I've been doing it long enough that I'm getting to know some:

• I work with about 100 other people, and I'm the only hard-core regular. But one of them rode a few times last summer and says he wants to start again soon.
• My LBS owner has been a bike commuter for about 20 years - my hero!
• I've spoken with a few others "on the road", but I don't see them regularly, nor know them personally.
• I have a once-a-week meeting at a large hospital, and in good weather there are usually at least 2-3 other bikes at the rack. Two of the others in my meeting (of about 12) actually are semi-regular commuters (in good weather), but I don't know who the others are.
• I've recently met a few in other contexts, but again, just acquaintenances, and they don't commute on the same route that I do.

I know from riding and driving in downtown Portland (Maine) that there are a lot of other commuters in the city, but I ride in an outlying area, so I don't see many on my normal route.
