A free wifi location directory for USA, Europe and the world. The information provided is very useful for business and vacation travelers who are in town. It has a large listing of wifi hot spots in cities and towns of states in the USA. They also cover countries in Europe, Canada, Caribbean, Mexico, Central and South America, Middle East, South Africa, Asia and Oceania.
As far as I know, common locations for free wifi are usually found in libraries, academic locations, hotels, cafes, coffee shops and restaurants. For laptop and PDA users that travel often, it is recommended to bookmark the site. One never knows when one may need it. =)
