Carfree.com would like to thank those who have contributed to making and improving this site:
Henning Mortensen whose help with Microsoft Access was invaluable.
My parents, Ann and Vance Crawford, Erik Rauch, Doug Salzmann, T.J. Binkley, Tony Brewer, Pete Menchetti, and others for their critique, research, suggestions, and support during the long gestation of this site.
J.S. Bach, whose music was an invaluable aid in writing this work, and the nameless nerds who went to the trouble to make MIDI files from it and put them in the public domain. Listening to Bach should probably be required while designing cities.
