I understand. I am the only one in the office or among my friends who watch Formula 1. But that's how things have been most of my life. No one in my office is into photography and only a small handful of friends willing to go out with a camera on a regular basis. I found community for both by going online. Your blog among many others, and the occasional photo walk, where I connect with other photographers. For Formula 1, I chat with people on twitter during the races. The #F1 hashtag is huge.
