Here are some links to people and websites that I’ve found useful:

Horizons Unlimited:  This is where I found my motorcyle from another rider.  It has good forums and information on other riders’ trips

Yes, there were two of them. They went that way.:  I met Patrick and Tara in Belize.  At the time they were just on a short vacation.  Now they’ve packed up and headed to S. America for a long term trip.

Traveling Ted TV:  I met Ted in Costa Rica–we both were headed to Corcovado National Park

Vagabond Journey:  I met Wade and his wife and kid in Colombia.  He’s been traveling for 12 years and has some good stories on his site.

Lonely Planet:  The standby for travel information throughout the world
