Enjoy - unlike any other place I've been in the world. Also the most visually intimidating course I've ever played, despite the lack of any really imposing water hazards. And they have some of the best, if not the best, food I've ever eaten.
Was lucky enough to play the member guest at Merion a couple weeks ago. We finished 2nd net in our flight, and 2nd gross overall, lost by 1 in both. No clue how I got so in the zone, but I was -5 on my own gross ball in fairly tough conditions going into 17 the 2nd day. Of course I choked and finished double-bogey for 68, but I'll never forget that experience. Just an unbelievable experience overall with food and hospitality, as well.
