You mentioned road bicycle, are you involved in any group rides? Tinkering with a thing was just an example. I've gone out of my way to join groups doing all sorts of activities that I also enjoy. Snowboarding. Scuba. Bicycle riding. I dare you to just open up meetup or facebook or something and just go find a group ride to be a part of. Here where I live there's a monthly group bike ride that seems like the entire town is in on.
