I've only ridden with others once since I started cycling again last June. That time was mtb riding on some local trails with some friends from work that I basically shamed into going with me. It was fun but we haven't repeated it(economic reasons have us all on different shifts now).
There's a local club I've been aching to ride with, but a guy at a lbs told me some of the people are rather snobby if you aren't on the newest and greatest, and I don't want to be put off and have it negatively affect my riding. So until I get much stronger I'll just pedal along solo. Maybe I'll find a partner to pair up with, maybe not. I'm having a great time already!
