Richard Bach, a former Iowa Air Guard pilot, said his best-selling book about a free-wheeling seagull was inspired by Mr. Johnny Livingston.

I acquired that label as a twenty-something private pilot flying a 1942 Taylorcraft L2 in the early '70's. I stopped flying when I got married and bought a house. I added it back when I started participating in a pilot's web forum.
I started flying in my late teens, early 20's, during the late 80's. Then I got married and bought a house, so I had to stop flying. The second child is potty trained as of this weekend (Friday, Saturday, and Sunday with no accidents) so my diaper fund is going back over to flying.
