Briefly. Padraig, I'm not sure what you mean by "heads down." Maybe that's intentional on your part . . . to see what different responses you'll get. In my own golf play personal experience, I see no change. With the guys I've played with over the years, from very skillful to not so skillful players, very few have ever been focused on the intricacies of the architecture ["subtleties of the course"]. . . or if so, they don't express it. Their oral conversations with others have to do with just about "everything under the sun" (mostly baseball, in my group, or maybe exchanging info about what their kids are up to) but they're still playing golf . . . not on their Blackberrys or cells, if that's what you mean.
