It was a perfect day with sun and a bit of cloud, and not too hot for climbing a few hills.   There was discussion about whether the hills were "steep" or not and it was generally agreed that one of them must have been steep since everyone had to walk it.  (Cross training exercise).  Some other hills were definitely rocky and require good tires.  Views were spectacular and the trail was very quiet, with only a few other speedy bikers coming the other way and a few hikers on the way back.  Great speed was enjoyed on the way back as we sped along the downhill double track.
