My friend Carey is a single Portland, Oregon mom with a mortgage, a short commute to a full-time job and two school-age daughters. That translates to a fairly mainstream transportation need. She's also my choice for TreeHugger of the week because as of about two months ago she finally found a way to mothball her Honda and get off the gas roller coaster ride by buying a Zap three-wheeled electric vehicle.
