they problem is, if you put this stuff up, people call you a lunatic... that's why I said, I'm all for a cleaner invironment, but let's get the facts straight. That said, us stupid humans can't clean up the invironment unless this fear of exstinction, however misguided or misrepresnted, sets in. Like hell, in a few years, everyone will be sitting at the stop lights, in their Hybrids, no sounds of motors idling, all quiet, and the air getting sweeter by the minute. (that's the opimistic side)
