OP
As someone with a bit of experience in these problems can the various clubs associated with the course not amalgamate and put together a financial rescue package to the council.
What level of joint club membership is there ? If it is above 500 it should be do-able with some joined up thinking and the assistance of the council.
You MUST keep the council on board so name calling and stupid comments by the golfers are a no no. They are doing a difficult job in difficult times.
PM me if you wish to.
