For me it means playing everything in sight new, good, bad, worse, and being really really honest about it. Playing the old stuff and trying not to cry at tree overgrowth and not to mark the course down because of the poor flora management!
It doesn't get you on Pine Valley, Augusta (Witness Mark Fine!), Shinnecock, Merion, Seminole, etc unless you can get on yourself anyway. It is not a ticket to free golf.
To do it right you need to pay attention to the course and not how you play. Betting, hitting only the ball you put in play, putting only the putts you have to only today's pin placement doesn't get it done right.
I like to play off times, sometimes in the rain and wind and cold and "bad weather" so I am by myself if I can be.
Interestingly, I often play very well because there is absolutely no pressure on me to play well, unless I play with someone who insists on playing for "$xyz", then i get distracted.
Some of my most fun times
-Playing Royce Brook West in the rain, by myself, walking.
-Playing a brand spankin'NEW NEW course not yet open even before media day with a person known to all here. Pr 3 tee boxes with one or two divots ONLY! Too bad the course wasn't as good as the day!
-Playing each of the two nines at Hollywood with two of their pros who can play and really really really play, respectively, elevating my own game and seeing everything I wanted to see on a really really good course with a really good restoration.
All in all, I really love the architectural aspect of the game and I take it seriously. Maybe too seriously, but once I got the bug about 20 years ago, the architecture is the thing for me. I always liked playing different places, have been lucky enough to be a member at 2 really good clubs and one shitty one. But..... I still like to pack the bag in the trunk and head out someplace new. Anytime, anyplace , I always learn something.
To do it right, it's not for very many.
