Lee,
You are correct, it is a very small world. Last week at Osh, my wife and I were walking down the flightline meandering through the aircraft waiting for SS1/WK arrival and I walked around a wing and ran into an Air Force (I am Navy) guy that I worked with in Japan a few years ago! Figure the odds.

If I had been one aircraft row away or looked left vice right I would have missed him. Ended up having dinner with him before he left the next day. Very small world, but aviation makes it smaller.
Take care,
Jim
