I feel really bad for the people who have to use the gas ones because they're breathing in exhaust the whole time. Small gas engines, especially the 2 stroke cycle ones, don't burn nearly as cleanly as the ones we find on most cars. And the people who operate those things are doing it professionally so they're likely to be expose to the exhausts all the time. The noise bothers me but I only hear them once in a while. I just feel bad for the people who have to deal with them all the time.
