I've played Pebble many times, but only once a few days after an Open. It was 1982 and I hit driver/9-iron to a back left pin position off the 1st, and pulled it slightly into the greenside rough, 15 feet from the hole. Took 7 (2 to get out of the rough and then 3 more to hole out from 25 feet or so). Hope they will have shaved the greensides (rough and chipping area) since I last played there (5 years ago). Otherwise, if the weather is as wonky as it can usually be expected to be there at that time, expect sugtrm und strang from the players, the pundits and you and I.
