There are reciprocal courtesies that many courses offer PGA members but certainly not anywhere we want. (I am a Class A PGA member.) It is entirely up to the individual course whether or not to offer any courtesies or discounts. The PGA of America is not involved in that decision. If a member or apprentice were to demand "free rounds" that would be an ethics violation of the PGA Consititution subjecting that member/apprentice to potential penalties up to dismissal from the organization.
At my course in Colorado we offer members of our section reciprocal courtesies and members from other sections across the country a significant discount. But we also severly limit both the number of rounds as well as the time of day they may be played.
Here at the the PGA owned facilities in Florida I don't receive "free" rounds-there is a daily cost I must pay. Less than the general public but an out of pocket cost for me, that I gladly pay.
Still like the Free Ride idea though...
