Pat,
Reminds me of Pete Dye's 12th at Stonebriar here in DFW. Blind tee shot, a valley cut in the hill seems to indicate the middle of the fw, and a cluster of bunkers to the right. Somehow, I knew Pete meant the correct line to be over the bunkers and hit it that way, and was right in the middle of the FW. Going through the valley would have put me left edge and further from the par 5 green, maybe the left rough.
On blind shots, I generally prefer a clue, and somehow this arrangement gave it to me, which is fine every once in a while. Had the obvious line put me in a pond or something, it would be bad. Generally, when forced into a blind tee shot, I tend to mark the route with a valley in the ridge, target bunkers framing, etc., and then leave more room for a miss, wider fairways, etc. It is up to the golfer to know via experience whether to shade to one side or the other.
Of course, my preference is for no blind shots, but sometimes you must, and if required, it does make for interesting variety.
