I used to ride Crafton Hills all the time! The most fun is when I had a hard tail mtn bike, I used to go up in the hills and then back around the orange groves. I lived in Lake Arrowhead (Twin Peaks, actually) but worked down the hill and used to do most of my riding down there.

I'm sorry I can't help you. I'm in Seattle now. I go down to visit my parents in Upland fairly frequently but don't have a bike down there. I really miss SoCal riding, I just don't enjoy riding up here in the rain.

Good luck! Have you tried any of the cycling groups? Or finding someone at an organized event? Redlands and the surrounding areas used to have a few metrics and centuries.

Hrrrmmm....Redlands Bicycle Classic is next spring. I miss that too.
