On the Montague plain and Willis Hill after dark with Bob Perry from Bikes Unlimited plus 7 others. Interesting experience, felt like a long interval workout. There was a modest range of abilities, with me certainly not the fastest but fortunately not the slowest, so we'd go for a bit and then the fastest would wait to group up. So I'd go as fast as I could to try to keep up, and then stand for a couple of minutes. I suppose I could have just gone at a nice even and modest pace, with no stops, but that didn't really occur to me. :-)
For about the first 4 stops I tried to stop/start the 305, but that got to be too much trouble and I just let it run. I think there's a setting I can put it on so it only goes when you're moving.
Beautiful evening, low 50s, clear, waxing moon. A mix of old jeep roads and narrower stuff, a lot flat, some up and down at the north end.
Quite enjoyed it. Knew a couple of the other riders (clients of mine).
Had my light on the handlebars. Some did that, some had it mounted on their helmet, not sure which is best (well, I suppose best is two lights, one each way).
