Yes, the sea is just on the left on the last picture. Like I said in the other thread, the course was right up against he beach. They are fighting the sand blowing in off the beach across the turf. In several photos, you can see the erosion control fences in the sandy area behind the green.
I recall now that most of the holes ran up and down parallel with the beach.
Nobody I talked to understands why the sleepers are there. They seem to be arbitrarily placed in some bunkers.
