We have an exception to not have to install adsb out for a while. Too many aircraft to do all at once. A lot of us have adsb in receivers for our iPad though.I live less than three miles from a National Guard reservation, and they regularly fly between 800-1500 feet over their normal flight path less than 2000 feet due south of me.
The military helicopters do *not* use ADS-B, and do not show up on AirSense or FlightRadar24. I just drop like a rock any time I hear them coming, since they're never flying very fast along that route.
