Probably my first several rounds of golf at Medinah, courtesy of my neighbors who were members. They didn't want to pay guest fees for their son/my best friend to take me out there, so we went on Mondays when the course was closed. You could play, but the clubhouse was not open.
We did that for a few rounds and then one fateful day we played no. 1 and no. 2, and then decided to go over to the famed No. 3 course, which doesn't return to the clubhouse. When we got to 17 tee, the long time pro, John Marshall, was sitting in a golf cart behind the green, waited for us to putt out, and handed me a bill for $140. That was a fortune to a 12 year old. One other "guest" of my friend was also there. My Dad made me pay out of my meager savings account. The other Dad stiffed our friends for the bill and decided his son shouldn't hang out with us anymore, probably to avoid pressure to pay.
In reality, that was the second thing Medinah and my dad combined to teach me. One, of course, honesty pays. Two, despite me begging and begging, even though Dad was a Campbell Soup executive and presumably able to afford the club his neighbor joined, he let me know that you take care of essentials before the luxuries, and wouldn't join. Probably the right call. Our neighbor was a really avid golfer, and later, also joined Bob O Link. Dad was winding down his golf career (as I was starting to beat him.....) and knew country clubs would be like owning a boat - not too many people can really use it enough to justify the cost.
