Yep I was wrong about the Great Horned Owls...for whatever reason I thought they were mostly on the east coast. I have a passive interest in photographing birds of prey and I never saw one in California. But apparently their range is the whole CONUS and most of Canada and Alaska too.
I'm happy to report that in my neighborhood, some Everytown for Gun Safety shills came on to try to drum up support for some meetings they were going to hold and within 30 minutes there were 3 posts telling them to GTFO. The thread disappeared by the next morning.
