Starting at 00:20 seconds in to this video, there are two angles of Brian Lopes riding up a steep section on the connector trail from Alta Laguna Park in Laguna Beach over to Meadows trail which takes you down into the trails of Aliso & Wood Canyon in Laguna Niguel. I rode that section for the first time in years the other night and was shocked to remember how steep and tall it is. Everyone in our group had to dismount and walk the 15 or 20 steps to get up it and we were talking about how easy Lopes makes it look. The video does not do it justice, and I have no idea how he does it, other than that he is Brian Lopes.
