I used to live in a rural mountainous area and would mountain bike avidly. There were tons of amazing and challenging trails. Only danger was a rattlesnake or I guess going off the side of the mountain but that would just mean rolling down the hill a bit in most places. That is it usually didn't mean falling to your death.

There were a lot of road cyclist who would bike on the tiny two lain mountain roads with blind turns where people would be speeding through. I always thought they were crazy risking their life like that. It just seemed better to drive to the trailhead and have a day in nature typically without ever running into another person.
