Who cares if the DZ on 13 is flat. Is it higher than the tee?
The only holes that are "flat" at PV are 1, 7, 10, 12.
There are small elevation changes at 9, 11, 13, 15 and 16.
There are major elevation changes at 2, 3, 4, 5, 6, 8, 14, 17 and 18.
4 flat holes, 5 that are somewhat "hilly" and another 9 that play over extreme changes in elevation.
But I realise that, having proclaimed "the sky is purple", there's no way you'll be backing down.
