I am planning to leave to Brazil from Washington, DC on bicycle on September 16th, 2006. I have already purchased a Koga Miyata World Traveller bicycle after much research and debate. I heard about this bike from a webpage of a couple on a bicycle tour around the world: Down the Road. The bike is very solid and well-equipped. I am very confident it will carry me to where I am going and farther.
Now I am working on setting up a relationship with an organization working on fighting global warming--perhaps environmental defense. I may have it that all contributions to my trip go towards a fund to purchase as large a block of carbon credits as money will buy. This means that all money raised for the trip will go to removing heat-trapping gases from the atmosphere, or sequestering methane emissions from cow manure before they escape. See Native Energy for more info on buying blocks of carbon.
