Thought some of you might find this interesting. The City of Memphis is challenging residents to go car-free during the month of April. People can take the challenge for one day, a number of days, or the entire month and will be eligible for prizes that help make carfree travel easier. In addition, there are 18 "model citizens" who will be doing the challenge for the entire month and blogging about their experiences - both good and bad, as well as prominent local people who will be participating on a more limited basis as their schedules allow.
Full disclosure: I am one of the "model citizens". I plan to use the challenge as motivation to consistently apply all of the non-car backup plans that I've already worked out, which means that I will probably be doing a lot more walking this month than I really prefer, depending on how much it rains. With one exception next week, I don't anticipate having any problems, since non-car travel is already a habit for me.
