Marine Corps Base Quantico. I’m in the area. Lots of Ospreys, FBI training and there is an occasional litter of cute little baby Lieutenants.
I’m directly under the flight path between Quantico and Langley but I have severe health issues and can’t be awake all the time. I see MV-22s frequently.
I probably live only a few minutes from you, although with the holiday traffic, more like an hour or so.
