Also known as a "Hummvironmentalist", this person drives around a Hummer (usually an H2, though rarely an H3, or even more rarely an H1) which is often left in 2nd or 3rd gear and is ALWAYS in 4WD mode, who has an environmentalist plate. This is sometimes thought to be contradictory, but it actually means that they want to preserve the national parks to drive their hummers in.
