he referred to "black diamond"
The ride leader can ultimately change the ride, but he is posting an "expert" ride at this time.
the trails at corral canyon are graded: green- easy (although harder than dirt roads), blue (more difficult) and black diamond (or double)... Some black diamonds at Corral are totally rideable, they just take a little more care
I'll be putting on a noob ride soon, where people can meet up, and gradually try harder trails under the watchful eye of some more experienced folks
Thanks, I was wondering if the black diamond was a difficulty reference. ill be looking out for your noob rides, and hope to make it
