It suddenly occurred to me that the Cheetah looks very much like a far less expensive leaf blower...hmmm. So I gave things a quick check and guess what? According to the little bit I have read, leaf blowers give out a lot of CO. Need to find out more. It would be nice to be able to eat for at least part of the month...smile. This machine would cost at least $500 more than I have at the moment, but I have gone hungry before, and for this purpose, I do not much mind going without food for 2/3 weeks. One bowl of rice/day, package of hot dogs and 3 loaves of bread...yes! I could do this...hehehe
