Maybe people in other places have better cycling manners? While part of me would love to have the kind of commuting paths I see posted here, my experience on 3 different paths here has been frightful. And that's just from the other riders. Let's not even talk about the runners, walkers, dogs, and kids. A few years ago, I occasionally would ditch my group ride and take the Minuteman into Arlington Center for coffee. It's an 8 mile ride to get to the start of the path for me, so doing that and riding to Arlington and back is 38 miles. Even at 10 AM on a Wednesday, I felt like I had to be hyper vigilant in a way that's different than when i am dealing with cars. Perhaps I am better at predicting what drivers will do.
Deb, that sounds like a nice ride for those who live closer to the city. I like reading about rides in my own backyard!
