doing a revolving pattern over our city block (1 square mile in these parts); it’ been doing this for roughly an hour.
This happens occasionally. Our part of town is pretty good and our subdivision in particular is nice, quiet and has very little crime. But thing go south badly if you head less than a mile south and take a downturn if you go north just a few streets. Given the population density, statistics ensure that some illegal activity is going to take place. The local PD is pretty good so I usually have no complaints.
But their helo pattern (some form of sector pattern based on the sound and what I’ve seen them do in the past) currently bring them over our house every 90-ish seconds, and they’re flying low. It’s loud.
