Ok ok ok, so you were at Washington Rock, not Watchung. Your post title is a bit misleading.
I was the solo guy. I passed you on the little bridge on the way back to the lot. After you ended your ride the pack of 8 was checking out your Surly.
The ride yesterday was really excellent. Almost everywhere I went I was the first trail out there which always makes the ride just a little cooler. Very nice day to be out, conditions were surprisingly good.
