Freakonomics is a great book. One of the things they discuss is the freakish number of world class (especially women) golfers coming out of South Korea. They must have a ton of golf courses there, right? No, they have a ton of driving ranges. You see, the repetition of building a swing on a driving range makes great mechanics. From great mechanics, the next step is transferring those fundamentals into action on the playing field. Last night, we did about a half an hour of nothing but fast downhill off camber right hand sweepers. Entry speed, line selection, commitment to the line, weight placement. If you "groove your swing" well enough in practice, you won't even know how to do it wrong under the pressure and fatigue of race situations. It's something that all of us pikers can work on.
Enjoy some footage of guys whose swings are pretty groovy, battling it out at Charm City last weekend:
