Jason:
Happy New Year to you too!
I hate being the party-pooper - chearleader is usually my role.
Just on this issue, well... for some reason I just don't want people to get the wrong idea. Sure the people at Cypress are exceedingly nice - if you have a reason to be there, or some other connection. Your brother's connection was his role in the golf world. If my brother - nice as can be, but as connected to golf as I am to his world (he owns some sort of internet-related company and is a contractor/presenter/speaker for Microsoft) he is to golf. If he tried to do that at Cypress, they'd politely ask him to leave, and then call the cops if he refused.
In any case, I really think the deal is have some connection, sure these things can happen. Dan King - as in so many things - has to be the exception, not the rule.
But bottom line is one shouldn't think Joe Q. Public can routinely tour private courses, particularly the REALLY private ones like Cypress.
Even if "tour" means walk a few holes, in this case.
