I'm also new to 'out there mbking'. I've been on the Fullerton loop and Telegraph (Carbon Canyon) both twice. Those two trails definetely showed me how out of shape i am! I'm cool Sunday mornings (7am) if anyone wants to creep at a snail's pace.
Hey, Silent, ShinKen, I enjoy riding Chino Hills/Carbon Canyon. Let's plan a ride some time. I suck too!!!
