I'm always the odd man out in these discussions. I'd rather walk a great course than play a good one. I walked Pebble twice - can't afford to play it, sorry - didn't play Pasatiempo. If I were in the area again, I'd play Pasa, but that isn't likely to happen anytime soon.
I'd always opt to play a great course multiple times over playing a bunch of courses once each. I do still fantasize over a trip to Scotland, and I'll be satisfied, no, thrilled, playing TOC, North Berwick and Dornoch and not seeing any others. If I make it to Cornwall, I'll play St. Enodoc multiple times before even looking into others. And if I ever make it down under, I plan to play Barnbougle and Melborne and little else, unless someone tells me St Andrews Beach is still alive... and I'll walk or play whatever Greg Ramsay is doing down there, too. Heck, I'd rather share a beer and dinner with Paul Daley than play any course in Australia.
Maybe all of this is because I'm not a great golfer and would just hope to shoot 95 on any good or great course. I'm hoping at least that much will change this year, as my wife has my little man playing the game, so that's a great solution to my never ending battle between my business and fatherhood...
