Gregg Bleakney’s dream was to travel the Americas from top to Bottom. He got the idea after he finished a long bike ride. Gregg’s friend, brooks Allen, also liked riding a bike. The two friends talked and made a plan: they would travel from Alaska to Argentina—by bike.

To pay for the trip, Gregg and Brooks worked to save money for a long time. Once they were on the road, they often camped outdoors and ate cheaply. In many places, local people opened their doors to the two friends and gave them food.

On their way, there were deserts, rainforests and mountains. They visited modern cities and ancient ruins (遗迹) such as Machu Picchu in Peru. And they made many friends from all over the world.

In May 2007—two years, twelve countries, and over 30,500 kilometres later—Gregg finally reached Ushuaia, Argentina. (Near Guatemala, Brooks had to go back and Gregg continued without him.)

The trip taught both men a lot about traveling. What did they learn? Here is some of Gregg’s advice:

Travel light. You should carry many things with you.

Be flexible (灵活). Don’t plan everything. Then you’ll be more relaxed and pleased especially if there are problems.

Be polite. one traveler told Gregg, “Nobody wants to fight or cheat a nice man.” It’s true.
