Langer, et al...
...you have reminded me of someone else who was "way ahead of his time." In western Pa there is a golf course called River Forest, not too far from Pittsburgh. The course was designed, built and operated by a fellow named Wynn Treadway, PGA. Wynn had some very strong ideas about how a golf course should be run, and since he owned this place, he ran it with an iron hand, and the regulars that played there loved him for it. What was Wynn's most important rule? PLAY FAST. In order to play fast, you had to have a working knowledge of the game, rules and etiquette, etc., and you had to be able to move the ball around the course with a fair amount of skill. Beginning golfers were not allowed to play there. Slow players were asked to return to the clubhouse because "someone left some money for them". Wynn would refund there money, tell them to leave, and only come back after learning how to play faster. Guys with long hair? No chance! Get a haircut first...then come back and we'll see if we can get you on that first tee. But the real reason for this post was to tell you about Wynn's teaching. If a beginner or inexperienced player came to him for lessons, they did not hit a golf ball for weeks. In fact, the first lessons were indoors, on the second floor of his clubhouse, in a large open room with no windows. The only thing in the room was a painted line on the floor, that continued up the walls on the sides. Wynn then had his student swing a golf club VERY SLOWLY that had a penlight attached to the shaft...in the dark. No golf balls could be hit until the student could demonstrate their proficiency to keep the light shining on the line, slowly learning to swing faster and faster and staying on plane. Now, Wynn was doing this BACK IN THE FIFTIES AND EARLY SIXTIES! He produced quite a few very solid players who would play good golf in a no nonsense manner. Sadly, this pioneer was murdered in his home by his own grandson ( a drug addict), who then committed suicide.
