While touring China, the President saw what he thought of as an excellent alternative to big gas guzzling campers. It was cheaper to run than a Chevy Volt–in fact, it could be run on beans and cabbage for the pedaler.  It sounded like a dream come true, the best of all worlds including exercise for the operator, until someone on staff pointed out the methane issue from the “processed” cabbage and beans that could cause global warming. . . . .  David, Sf.G.
