So those who can bike when it's practical and drive when they have to. They don't buy the biggest, gaudiest SUV and then fire it up everytime they need to go two blocks.

My Dad never realized he was a great conservationist when he'd growl "turn the darned lights off when you leave a room", but that's what he was (and still is, thank god...). It's all about common sense and paying attention to the COST of things, as well as the price.
