    Many people dream of going on a great travel adventure. Most of us keep dreaming; others make it happen.

Gregg Beakney's dream was to travel around the Americas from top to bottom. He got the idea after he finished a 1, 600-kilometer bike ride. Gregg's friend, Brooks Allen, was also a cyclist. The two friends talked and set their goal: they would travel from Alaska to Argentina by bike. To pay for the journey, Gregg and Brooks worked and saved money for years. Once they were on the road, they often camped outdoors or stayed in hotels. In many places, along their route（路线）, local people opened their homes to the two friends and gave them food.

During their trip, Gregg and Brooks cycled through deserts, rainforests（热带雨林）and mountains. They visited modern cities and explored ancient ruins（遗迹）, such as Tikal in Guatemala（危地马拉）. In many places, they met other cyclists from all over the world. In May 2007, they traveled twelve countries in two years, and over 30, 500 km（19, 000 miles）. Later, Gregg finally reached Ushuaia, Argentina, at the top of South America. Gregg and Brooks kept a record of their adventures in an online blog. The trip taught both men a lot about travelling.

Here is some of Gregg's advice:

Travel light.

The less baggage you have, the less you'll worry about.

Be flexible（灵活的）.

Don't plan everything. Then you'll be more relaxed and happier, even when there are challenges along the way.

Be polite.

A traveller told Gregg, “Always remember that nobody wants to fight or cheat a nice guy”.
