Raking or using a broom is indeed actually easier than blowing leaves most times. I have a blower, but only use it for that purpose once or twice a year. My blower is actually most useful when I reverse the attachments so it can suck up and shred leaves before bagging them.
As for using a leaf blower after 9 p.m., I’d be pissed also. I would first complain to a senior Safeway manager, and if that didn’t resolve the problem I would file noise complaints with the police and city. I’d also get your neighbors to complain so they don’t just think they are disturbing a single “crank.” Good luck in resolving that, Jan. I hope your issue gets resolved.
