I'm a feel player with a strong appreciation for minimalism and/or the natural in golf and golf courses. But mark the damn sprinkler heads, there going to be there anyway. Take the 150 stakes and burn them, tear out the 200, 150 and 100 yd plates, but mark the sprinkler heads.
There is a definite skill in visually determing distances and I often practice shots inside of a 100 yds without looking for the yardage just to develop feel. Plus on a hilly course you've always got the elevation change factor, and then there is always wind to consider. My pt. is that there is still enough art left in the game for the USGA to require that all sprinkler heads be marked. Call it the one constant in the playing field. There is nothing more frustrating than playing a new course, where there are no caddies and your stuck on cart paths only, walking across the fairway with half your bag in your hand and not being able to find a marked sprinkler.
The game is difficult enough with exact yardage!!
