LILLIAN, Ala. — Robert Frost suggested taking the road less traveled to change your life. Two French natives have taken that advice to heart and are traveling from Miami to Argentina — by foot.

Armed with ten pound backpacks, a tent, hot plate and a high-tech video camera, Laetitia Casareto, 23 and William Guimaraes, 26 from Bordeaux, France have given themselves two years to make the more than 5,000 mile trip, spending 90 of those days in the U.S.

“We walk 20 miles per day,” Casareto said. “Around four or five, we stop and knock on American family door to ask to put up a tent in the yard. We never ask for bedroom or anything else. We just knock on one or two doors before they say yes. In big city, it is sometimes more because they are maybe a little afraid.”

The duo entered Baldwin county after crossing the Perdido Bay bridge. The first door they knocked on was a Lillian woman’s who invited the two in for showers, dinner and a room to sleep in; an offer that was a welcome surprise.

“We heard and read and see TV in France and saw a lot of things about American people; we think it’s violent with lots of guns and they maybe are not kind,” Casareto said. “But we are very surprised Americans are very nice, they give so much. There are only a few bad people in the world. Most people are very, very good.”

The trip began on September 27, when Guimaraes and Casareto arrived in Miami. The trek through Baldwin County had stops in Lillian, Barnwell and Spanish Fort, before continuing to Mobile. They will conclude their trip in the US in Texas when they cross the border into Mexico.

They don’t carry cell phones, only iPods which they charge using solar power. They don’t sleep in hotels, stop for tourist attractions or eat in restaurants. With this philosophy, they spend only $6 a day each. Rest stops for water are made at local gas stations and boxes of rice and pasta are bought every few days at local grocery stores.

However, Casareto and Guimaraes will make one special exception when they finally step into Louisiana.

“We want to try alligator,” Guimaraes said. “So we want to make stop in New Orleans so we can try alligator there. It sounds good.”

The two-year trek through the Americas is not the first for the couple. They previously spent six months hitchhiking from France to the Maldives, India and Sri Lanka, before returning to Bordeaux.

“We already had two expeditions, after we decide to make special expedition in America, we say why not by foot?” Casareto said.

Guimaraes has mounted a small lens on his backpack strap, which is hooked up to a camera he carries on his side, to capture every step.

“At the end of the trip we want to make movie,” Guimaraes said. “Every few days we talk to people and make short movie to go on Internet, we love to meet all the people. ”

When they eventually reach their final destination of Ushuaia, Argentina — the southern most part of South America — they may head home.

“We don’t exactly know what we will do after,” Guimaraes said. “Maybe we will take a boat home, we don’t plan. Life is very short and the world is very big.”
