I go it alone too. None of my friends are remotely interested in cycling or even a casual ride on a nice Saturday. I would love to find a friend or two who wouldn't mind riding together but I also work with girls who have no interest either and I'm too chicken to try to get involved with some sort of organized group. I really don't mind riding alone, it's usually a good time to clear my head and just take in the scenery. At the same time it would be cool to have a friend or two to challenge me to ride longer every once in a while.
