This allows Augusta to let flowers bloom and greens not to die so when the masters come around in spring the course can look good. One fact is that when the winter storm happened in Atlanta this year and iced everything over it was 20° outside and on the greens at Augusta it was a solid 70°.
They control this from a room inside one of the cabins and a shed in the trees around hole 12. This year the course looks better than ever for the masters.
