Some sites I find useful and entertaining:

www.ibike.org/links/travel-bikes.htm
A page full of bicycle touring links.
rolfpotts.com
Travel writing and information by Rolf Potts, a self-proclaimed "vagabond" whom I met in Thailand.
lonelyplanet.com
Publishers of some of the best travel guides. Their site contains a wealth of travel information, as well as the Thorn Tree, a message board for travelers.
travel.state.gov
Travel advisories from the U.S. Department of State.

If you know of any good travel resources or interesting travel-oriented sites, let me know.
