My wife is currently cycle-touring Mexico. I would have gone but I had to Hold Down the Fort, a very important job. Anyway, yesterday she and a friend did what several locals had claimed would surely end in death -- they rode their bikes in Mexico City traffic. They pronounced it doable but not comfortable. Mexico D.F., as folks who have been paying attention to this site already know, also features a bike path of note. When traffic is heavy drivers enjoy using the space. She sent along some pictures of that and some other attractions, including policia en una Segway. There is a helmet law in Mexico City too. People don't need to hear how I feel about that again. The bicyclists generally ignore it I'm told.
