Nice article and slide show in the New York Times about that other California ride of choice -- the Zamboni: http://www.nytimes.com/2009/05/23/sports/hockey/23zamboni.html?scp=1&sq=zamboni&st=cse [imglink]http://graphics8.nytimes.com/images/2009/05/23/sports/23zamboniB_xl.jpg[/imglink]
The ones used here run on propane gas. I wonder what the mileage is like and does the consumption go up in winter?
I used to drive one at my old job about 5 months ago. Ours ran on CNG as did our F150 work truck. We had a filling station out back. They're not bad, I've gotten one sideways before on the ice.
