Sum ting wong, anons. I live on the east coast not far from major water, so it ain't terribly uncommon for MIL choppers to pass over my house, but this shit has been every hour on the hour since before dinner. Now it seems it's ramped up to half-hourly the last hour or two, and mind you, the time is well after midnight. Maybe it's just some night training, but who knows at this point?
