Did an abbreviated version of this ride today, both of those climbs are super nice, I was quite surprised. I parked at a park in Pine Mountain Club instead of starting down by the 5. I think the herdest part of this ride is the 15% kickers (both directions) between Mt. Pinos and Pine Mountain Club. This starting point worked out super well, as I was able to grab a coke and refill my water at the store there in PMC.
