I'm in Wilkes County now and Florida in winter. Have just started, 3 rounds. Played twice at Rock Creek, very nice and only $12 weekdays and $15 weekends. Hilly course, price includes cart.
Membership fees vary. If you're talking about class A golf courses that could run to thousands of $$$ annually. But there are friendlier rates like the one near my place charges only a little over a thousand a year.
