That's a great piece, Jean.
I've never lived anywhere with this type of bike infrastructure. There's essentially no bike paths here. Well, there's 2 sort of near me (within 5-8 miles) that I avoid like the plague because one is just congested and the other parallels areas where I am already riding on the road. Right now, my town is fighting the extension of this path through our town because people are afraid that users might "pee on their lawns."
I did experience this type of riding in Boulder, a few years ago, when we took one of the kids there for a college tour. I had not been riding that long and I was amazed by the ability of people to commute by bike there. For now, my riding will remain strictly on country/suburban roads.
