"Does the configuration of the "Road Hole" green allow it to be placed anywhere, at any orientation, irrespective of par?"
Patrick:
Of course, you dimwit. I already explained that to you right there standing next to it at NGLA about five years ago. I even explained how to use it as a par 3 (which we just may do in Maryland) and I explained how it mimics the concept of Pine Valley's 1st green if approached as a long par 4 from the opposite direction from the par 3 concept (that is from the direction of the middle of the 11th if you can't even figure out what the opposite direction means).
On the other hand, you said the green would work great if approached from the direction of the Bottle hole. That wouldn't work at all, everybody would hate that concept, and it would be completely panned right out of the box so it makes sense you thought of it.
Consider the Short at NGLA. It would also work great in a number of iterations if approached from either its left or its right, but I don't think it would work at all if approached from behind in any iteration.
Furthermore, it's not particularly polite of you to just borrow all the interesting things I've taught you about architecture and try to make it look like you thought of them.
