I think there is a lot of context lost on most golfers, much less the general public, when it comes to history and name recognition of various courses.
I know we all run in different circles, but most weekend golfers I've known thru work, friends, and otherwise, have never heard of Cypress Point or NGLA, much less know anything about them. The vast majority of the golfing public know about courses in their extended area, and then what they see on TV...and it typically ends there.
But i'm not surprised by it, we all have our select interests that we deep dive into, and everything else is just surface knowledge.
P.S, Its certainly been amusing seeing some of the chats about stuff like beer in this group over the years....I'm guessing most in the treehouse haven't taken the deep dive into that...
