Our household gas expenses are relatively low. We don't work far away and live within walking distance of grocery stores, restaurants, bars, etc. We walk whenever weather permits.
No wonder Americans keep getting fatter, most suburbs are not walking friendly! American lifestyles are becoming very similar to feedlot beef raising:
Cows: Diet high in corn and minimal movement(confined in a barn) means a fat, tender cow.
People: Diet high in corn (corn syrup, corn chips, corn oil, corn fed cows, etc) and minimal movement (confined in cars and cubicles) means a fat, tender human!
