There are still areas in the USA that heat their homes with wood. I live near one, luckily just far enough away that I'm not sitting in the haze of smoke. I don't know how anyone can live in this town in the winter.

As for 2-storkes, I can't stand them, but they are still a necessary evil in many situations. I have gas and electric chainsaw. The electric doesn't compare in power and capability - but it is also my favorite, so I use it when I can. I love not smelling like 2-stroke exhaust, the electric always "starts" too. Then a larger tree dies or a dozen blow down at once and I have to break out the gas saw...
