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
