How to Wash a Croc and Other Cool Stuff

Getting Around

Hopstop.com tells you how to get anywhere by mass transit in New York City, Boston and a few other cities as well.

Kayak.com searches hundreds of travel sites (airline's own sites and sites like cheaptickets.com) to find the best deals. It also produces a graph that shows you how much the prices have varied over the past 90 days, so you can see if it looks like that particular day is a high spike.

AirfareWatchdog.com comes out with unadvertised fare reductions and other airfare sales for domestic and international travel. It also fields questions on air-travel problems.

But you'll almost always get the cheapest airfare from an airline's own Web site.

The Web site of the FAA's Air Traffic Control System Command Center shows where flight delays are all over the country.
