My concept of it is, you lay out a golf course on ground like Sand Hills. You design a course with drawings and detailed plans.
I'm thinking that guys like C&C (Sand Hills), Bunkerhill (Wild Horse), Doak (Ballyneal-Barnbougle), Strantz (Tobacco Road), did more laying out on those than designing. Yet, C&C or Doak also design. Maybe Tom Doak will come on here and say if he has "laid out" a course and which ones. Of course he and his team design them with very fine detailed plans mostly (like Rawls at TT).
Bendelow was a lay out fellow, Ross was a design man.
