There are no formal tee markers, although each hole has multiple formal and innumerable "informal" teeing grounds. Since there are no course ratings, there is no limitation to the various combinations and yardages that might be played in a given round, and over a number of rounds.
Many of these teeing grounds are widely disparate in either yardage, angle, fairway exposure, etc and it took some time for my fairly rigid way of thinking to adapt to some of this flexibility--by the 3rd or 4th round the benefits to such an approach at Ballyneal were obvious. I don't believe the same approach would have any usefulness at West Seattle, for example!
In our rounds, either one of the hosts picked the markers to give us a wide variety of experiences over the rounds, or we let Dell Sims pick a tee box that would play to his strengths, or we simply watched in awe as Matt Schulte teed off from a road, a yucca plant, the edge of the previous green, the roof of the Turtle Bar, the rest shack, or wherever else he came up with...
