I've posted this before.
I regularly fly into a few non-towered airports where you don't EVER use your tail number.
I will post a cash bond and guarantee that if you do use your tail number, you will get a call from the FAA, sometimes before you get your plane parked.
Around these airports there are rich people, in big houses, who hate airplanes, who have nothing else to do except record your tail number and call the FAA to complain about the noise, crazy flying, dangerous maneuvers, terrorist activities. Seriously.
Guess what? The FAA is staffed with career idiots who haven't got the sense God gave a toadstool, and will never question the veracity of those reports. They have your number. Boy, oh boy, do they have your number.
Personally, I don't have time to deal that that crap. I'm too old and too crotchety, and don't have much patience for petty bureaucrats who feed at the public trough.
I'm "GBR, yellow Cub 111 (last 3 characters if there are more than 1 of us buzzing about), 4 miles out to the south at 2,000 feet inbound, GBR. or whichever of the airports I happen to be focusing my terrorist, noisy, dangerous, crazy activities that day.
If that offends anyone, I'll just turn the handheld off and really screw up your day. Most modern pilots can't cope at all with someone who is NORDO.
