Rich -
I would think there are any number of well placed drop dead gorgeous bunkers at Cypress, Royal Melbourn, Pasa(?). The fw bunker on the 3rd at ANGC. MacK's old bunker on the 10th at ANGC would have met the standard until the green was moved by Maxwell. Now it defines eye candy.
Add a number of bunkers at Merion (1,2,10, 13, 15). PVGC (3, 6, 7, 8, 16)
I think Strath, Hell and the Road bunkers are all gorgeous. But maybe that's just me.
I could go on.
But if your point is that there aren't many such bunkers, I certainly agree.
