I think one of the best ways to get more girls on bikes is to conitnue doing what we're doing - biking AND being nice. I'm lucky that my LBS is super fantastic and supportive of all cyclists. I also had a great run-in with another female cyclist at a crit. She was the only other woman there. She was super helpful and nice. I did horribly in the race, but I had fun! I probably wouldn't have entered had I not asked this lady about how the whole thing operated.
