For average player, what is that anyway 15-20 hdcp, the mounds can come into play, especially into the prevailing wind from the west.
Oddly, a new 'back' tee on the 15th turned out to be too much for the good players due to the carry. Into prevailing wind, the mounds are almost 5 feet, it was quite a carry and the new back tee was abandoned. Most do not even notice the abandoned tee. Another new back tee is contemplated, more in line, or just behind present back tee in use.
Most golfers at HH walk although I do not have the numbers on cart rentals. Quite a few 3 wheel, now 4 wheel, 'speed carts.' Total rounds hover around 24-26,000 although a number of late afternoon rounds in the summer might be missed.
HH is an easy course to walk, with short distance from green to tee, and no mountains to climb.
