I agree with Sean that it helps to have space around the landing area of a blind drive (and would add, perhaps even a bit of containment, or at least not much in the way of run-offs). For those who've been to Kennemer in Holland, the sixth hole on the A nine (the one that was built after the war by Frank Pennink, though largely following a routing plan of Colt's) has a blind drive through a fabulous saddle. It looks great until you get to the landing area and find that the hole turns quite hard to the right and your drive may have run away from you.
Colt's original plan called for the hole to take a different path between tee and green, to the other side of the knob that forms the right side of the saddle. Frank Pont, who consults at Kennemer, hopes to rebuild it in Colt's corridor. In some ways it's a shame, as, from the tee, the drive through the saddle is really inviting, but the landing area is far from ideal.
