Seriously man....do you really think that you are part of a solution? Do you think that the cloud of smog I see hovering over Chicago and Milwaukee when I look out over Lake Michigan from SW Michigan is due in any significant way to 2 stroke engines? If you're that on board, go ride a bike, and know that the rubber on the soles of your Birkenstocks will not biodegrade for 5 million years and sweatshop children harvested your patchouli. When they pass the Polar Bear Adoption Act, due to polar icecaps melting, I'm fawkin gettin one...always wanted to hang a, "Beware of Polar Bear" sign in my window...then maybe my 2 pitbulls will get a break from being ridiculed by the ignorant and misinformed.
