Most Americans play "parkland" courses with "penal" designs where bunkers are evident for all to see at the side of the fairways.
Hence the reason that "blind" bunkering would not work at a CCFAD or public where a lot of people will probably only play it once.
I would imagine that most American golfers have issues with ANY bunkering in the fairways, nevermind blind bunkering.
Sean L - I forgot about 6 at Trails, I guess that is one of the benefits/shames about having a "Yardage Book" where you can see the layout of the hole. I remember thinking, whatever you do, don't hit it in that bunker over the rise, and I ended up rolling to about 2 feet away.
That was a fun walk from the tee to the rise to see what happened!!!
I love that kind of thing every now and then.
