I just want to encourage you to keep looking. That woman with the bad attitude does NOT represent most bike clubs. I was at my local shop last week, discussing my own return after a layoff of 9 years. The extremely fit male who happened to be working at the time invited me to ride with the group. When I pointed out how out of shape I was, he kept on, saying that there are certain points along the usual routes where the fast riders wait for the slower (slowest, in my case) ones.
So, for every idiot out there, I think there are probably 10 times as many supportive cyclists willing to share their expertise and fellowship. Keep looking for another group, and good luck.
