A traveling salesman plans to attend a conference of traveling salesmen and wants to drive from point A to point B and back using the shortest, quickest route possible. He first tries the obvious tool for the job, Google Maps, which times out unexpectedly. Yahoo! Maps, Live Maps, and MSN Maps all do likewise when given the same query. MapQuest returns a more helpful 500 Internal Server Error after a few minutes.
