We had the same thing here last night.
~~~~~~~~
my locals have been still for weeks. maybe they’ve departed.
Four Fridays ago, in the evening. Sounded like it was right on top of my house. Very loud. Drowned out the high-schoolers driving down Main Street. Odd that the sound remained stationary for nearly 30 seconds.
Did not go outside to see what it was. Not scared exactly; it was more like it just seemed like a better idea to stay inside. Can’t explain it any better than that.
