One of my closest friends does off-roading... the serious kind. Tom builds these monster Jeep thingsand goes up and down mountains and over rocks where no sane person would ever try taking a vehicle. A few years ago, he rolled his Jeep down a mountain... about a mile until he hit one of the few trees which stopped his rolling.
Well, to prove he isn't the craziest person in the world (even if he is the craziest I know) he sent me this link where a Jeep drives across water.
Well, Tom is right. He isn't the craziest person in the world.
