There are earlier posts of mine about gas-powered leaf blowers: read them here and here. Washington, D.C., recently enacted a ban on gas-powered leaf blowers, to take full effect by 2022. The journalist James Fallows and his wife Deb were among a small group of neighborhood activists who started working toward this in 2015. You can read here a short article by Fallows at The Atlantic with links to additional information.
Recently, Tree Watch sponsored a somewhat biased survey on leaf blower use in Inman Park.
Opinion was sharply divided. To say the least!
