You've
really never spent any time outside of a city, have you? I can take you to places where the roads are nothing but oiled dirt, try driving your Lexus (or whatever you drive) down that shit.
For that matter, try putting everything you would need in terms of food, water, clothing and equipment for two people for nine days in/on whatever you drive then hit a primitive campground.
Wha's a matter, Plunk, you ain't got Red to razz anymore so you're going to pick on the board's other out and about liberal? I don't need to justify my lifestyle, I'll gladly compare carbon footprints any day of the week
