A few years ago I came across an on line ski instruction book. I downloaded it. It was written by a ski instructor from either Aspen or Vail. It was one of the best ski instructions I have ever read. My old computer crashed and I lost the book, tile, and author. I would love to find it again. The authors main point was the essence of skiing was turning and the essence of turning was edging.
I know I haven't given much information here but has anyone come across this book and can tell me where I can find it?
I also lost my Excel spreadsheet that calculated a ski's radius and surface area. I have found the formula for radius and entered it in a new spreadsheet. I still haven't found a formula for ski area surface. Does anyone have one?
