Words to live by, learned from a master
Although Bob was not a CFI, he spent many hours of his own time sitting in the right seat giving me the best instruction I ever received. He never charged me a dime. Well, that is not completely accurate. When I was preparing for my Instrument Rating, Bob told me to bring a roll of dimes. “Why do I need a roll of dimes?” I asked. “Because every time you deviate more than ten degrees from your assigned heading, you have to give me a dime.”
