Probably irrigation of his 1.85 acres.
From NPR:
“Audubon International estimates that the average American course uses 312,000 gallons per day. In a place like Palm Springs, where 57 golf courses challenge the desert, each course eats up a million gallons a day. That is, each course each day in Palm Springs consumes as much water as an American family of four uses in four years.”
Golf courses are a waste of land and water resources. BIG TIME. It's private property so they can do what they like. I wonder if those jerks get exemptions from property tax and WATER bills.
