When I moved out to the western suburbs of Chicago back in the early 90's, there was a muni course near me (Fox Bend GC, Oswego, IL) that after the close of their season, set the course up backwards for winter play. It was a blast! The tees were in front of the green and you played back to the tee where they had cut a hole an placed a flag. There was no charge, just show up and play.
One cold, windy, rainy, winter's day, I went out and played. After a few holes, I looked back and saw a twosome, and thought, who is as crazy as me and is out playing golf. After a closer look, I realized it was my new next door neighbor and his brother. Needless to say, a terrific friendship was born!
