I don't trust people enough to road bike like a lot of people do. A lot of people i know go on long rides on the weekends and ride down the shoulder of a 2 lane country rode. Doesn't sound like fun to me.
Since i moved to a city with plenty of terrain and good climate, i go trail riding a couple times a month. It's great exercise if you keep a good pace. I'm just not a fan of riding in town, seems like a good way to get ran over.
They have some downhill bike courses nearby the ski slopes in the summer, pretty intense stuff. Looks like fun, but i haven't tried it yet. Some people travel from all over the states to hit these slopes, they are good people, lots of hippie types living out of a travel trailers. Met a few cool people just trail riding around. Very down to earth people.
