Regarding pollution and motorcycles, I recall there was an article in the Toronto Star a few months ago and they made mention of the fact that they were really bad for pollutants, the worst I believe were those scooters...I think they said they were actually about 15 to 20 times worse than cars/trucks/suvs per mile mainly due to the fact(here anyway) that they weren't subject to the much more stringent requirements put on autos.

Half of communication is listening. You can't listen with your mouth.
