Thanks for pointing it out - must have it!
Heaton Park I know well. It was a municipal course (designed, I believe, by J.H. Taylor) and was in a pretty lamentable state but it was (if my memory serves me correctly) taken over a few years ago and is now run as an inexpensive pay-and-play course. There are several other more extreme holes than the one illustrated. That one is an all-or-nothing long iron over a pond far below with impenetrable rhododendron bushes as well if you don't make the carry. There's also a hump-back par 5 where you drive up a steep hill and almost all of us will then be playing totally blind over the summit. The ground then plunges down even more steeply into a great chasm, the green being perched somewhere on the far side. But the maddest is a right-angle dog-leg played totally blind over a bank of rhododendrons with the green driveable if you know the correct angle and terrible fates awaiting the ball only a few degrees off line. When I first played there many years ago there was a gipsy encampment in the low ground in the angle of the dog-leg and it took great courage to risk the carry...... There are rather too many blind shots for safety with the mix of abilities found on an unrestricted course, but it is full of character.
