i don't think i've ever "actively" converted someone, but i think my dedicated commuting encouraged some others who were already cyclists to try commuting or some part-time commuters to try full-time.

when i was in Portland it was pretty easy to "encourage" someone since the city is good for commuting and the attitude is very pro-cycling and pro-environment and the strong CAR-CULTURE of most of suburban america is comparibly weak in Portland.

also at the university i got some students who already rode bikes but only on campus to "commute" for off-campus stuff when they had never thought you could ride across town to the dentist or the shopping center or whatever (Texas... where you drive from one end of the strip mall parking lot to the other b/c who would walk when you can sit in air conditioning in style and listen to radio and look cool all at the same time getting someplace?)
