On the other side of the world, Internetters can piggyback on a three month bike-riding expedition through Mexico and Central America. Not that the five-person Maya Quest team doesn’t have enough to car : in order to maintain an Internet connection, their travel gear includes a satellite dish. Students on Prodigy will electronically advise the team to make pit stops and detours; other students on the Internet from 40,000 U.S. schools will tag along.
