Heck, it is hard to nail it down to one hole........there are so many great holes.....and it is a pleasure to play any of them.
Merion, Congressional and Pebble Beach for full stroke play courses have some sensational picturesque holes......
Then some of the CTTH courses have hole to die for as well.....like music, just too hard to state a specific hole....good thread Gary
p.s. any hole that yields a birdie is a good one for me :))
