heheheeee.... me too, Jack!
We're under the approach to an airbase here: I ~ALWAYS~ I.D. the craft from the sounds, be it rotor-wing or fixed... friends think I'm prescient (or NUTS!). It pays to know what's overhead!
Another 'thing' is: If I exit a less-used door, I will ALWAYS look UP... a fifty-ish non-serving friend remarked to me one day: "I notice when you walk out the back door here, you always look up. Why do you do that?"
"Old habit." sez I.
He got a kick outta the explaination that followed. /ubbthreads/images/graemlins/jester.gif
