I have played the Frog twice, which should mean that my feeling for the course is marginal. But I have generally been underwhelmed. I hope I am missing something and would like to get back to find out.
To me the Frog's assets are:
1) Generally solid
2) Very well maintained (even if the budget has been cut. If so, credit goes to the supe and his guys).
My impression overall is that there are not that many memorable holes. It's just kind of bland.
#2 really is intriguing, and maybe the best hole out there. Too bad Fazio couldn't have translated what he did there throughout the course.
#4 has the potential to be a really fine hole, but the landing area is too tight, pinched.
#5 to me is flat-out boring, and #6 seems to be another missed opportunity. if you kill a driver you might make the green, but if you don't it's one of the wimpiest little wedges possible.. even if the defenses around the green are pretty ok.
#7.. i want to pull out my hair and say "so what?"
#8 is a really good par 3. #9 is tough and solid, but that's about all. i don't see much character there and that's my overall problem with the course.
To me, the back nine takes the front nine's blandness to a whole new level, the one exception being #12 (I think), which is a very satisfying par-4. #13, the par-5, I have to DQ myself because I have played it horribly and can't comment other than to say that I hate it.
After that, there's really.. nothing.
#18 could be a really nice hole, except that it's too long, at least for me, to have any risk/reward. It's basically a drive, 7-iron layup and wedge to an interesting green. But again, so what?
I just don't get it. It seems charmless to me.
