For the folks who worried that helicopters (from PG&E it turned out) above Quincy meant a nearby fire, I would like to recommend a website/app called WatchDuty watchduty.com that uses input from firefighter, sheriff, and Forest Service scanners as well as satellite data. It is updated continuously 24/7 with information about fires all over the state of California.
It’s FREE (although they accept voluntary donations). I’ve gotten a lot of peace of mind– after the past couple of fraught summers– by checking WatchDuty this year.
