Adam, Yes absolutely yes! I think the quest for yardage while on the course has made the game slower to play as well as taken away its charm in this regard.
I think yardage books should be disallowed from all humanity other then being sold in the pro shop for reference and dreaming when at home! I think sprinkler head yardages are also a bad thing, and I blame this on the early to mid-1980's when the trend really got started. It has slowed the Sport of Golf down immensely, and harmed it the same way one goes about covering their body in tattoos, thinking its going to make them look good.
And just like a tattoo, its irreversable, so, this is why its probably best to keep on designing for illusion for the few out there that can respect it as well as praise it; the few that don't want the beautiful body of Golf marked and defaced. Stay true to your path, stay true to Golf.
(All in all, probably a horrible analogy, but one the mood that I woke-up in this morning!)
