Join a trek study, travel for free! {Gadling}

Jan 22nd 2010 6:55PM There already was the same study for U.S.and Canadian residents (Phase I and II) last year, but this study is only for people living in the UK or Germany.
But you can asked them if they are planning another study for Americans. (I found a website about the same study for people who want to travel to India, just look for Trek Study and India).
