This stretch of trail is only four miles long, so after a couple loops you can pass the same rider three or four times. Most folks are friendly. I got "howsit goin?"three times from the same guy. He got "hey" two times and one "howdy.
Most everyone else was on a proper road bike, but even on the pavement, I like a little extra rubber. Big tires are more practical. I also find that tire volume directly influences my joy-factor.
