On the way home, I saw another older rider wearing headphones (and no helmet) cutting across a major intersection (riding in the striped lane down the middle of the road, then turning on to the MUP). As I caught up to him, I had to go across the other lane and into the grass, since he was riding down the center stripe, and generally weaving back and forth.

Also came on a guy using a 2-stroke assist motor on his bike - they're illegal on the MUP, but I was tired of playing cop for the day. Someone else can worry about him......
