Some of Fort Worth’s municipal golf courses could become victims of the city’s budget cutting. Fort Worth has five municipal golf courses, and three of them are losing money. City parks director Richard Zavala  says they’re looking at shutting them down if they can’t be made profitable.   Zavala says the two biggest losers are Sycamore Creek and Z. Boaz, losing a total of about a half million dollars.   But it’s not as easy as merely raising greens fees. Golfers will merely go to other courses.  He says the problem is an abundance of competing golf courses, and not enough golfers.
