Mother Earth needs your (my) help

Today is Earth Day.  Even if you're not the typical "green" citizen, you should feel obligated to own a mode of motorized transportation that gets better than 12mpg, like my cars do.  The peer pressure to give in to the magic of the MadAss is strong.  How much longer can I feign deafness to the MadAss's siren call?  I don't know, and I don't want to find out.
