Interesting thread.
Peter -- One of the things that strikes me as a read this is that this group is about the worst possible focus group for this question or point of view. For example, various posters mention Streamsong and Bandon -- which only a small portion of the golfing public ever really see. They are busy places, but most of the guys that I play with, or know, haven't been to either, let alone both. I (and many of the people o this board) have been to both. Also, I think the people on this board would be wildly over-representative of those who travel to play golf as a key part of their life; or as something they prioritize above other things. If you are interested in the study of GCA, you must travel -- that's just the way it is, unless you live on Long Island, or in the Melbourne Sandbelt, or the coast of Scotland. And even still, to get the variety we crave, you have to get on a plane.
Wayne -- you mention St Thomas and Redtail, and Peter mentions two Thompson courses (I assume they are Cutten Club and Westmount). I happen to be a member at St Thomas for the exact reasons mentioned by many posters: great local atmosphere, fantastic course, support great GCA in an area that needs it. Retail's current rate is about $15K a year to Wayne's point, and my out of town membership costs me $1600 a year at St Thomas -- leaving me $3400 left in Peter's hypothetical budget for some travel. And that's about what I spend, giving me the best of both worlds.
In short, I don't know many guys that call themselves golfers that give up their 30 rounds a year at a local course for a once a year blowout to Kohler or Ireland. I think most of the travel is done with disposable, discretionary income; while the local club comes out of the more "fixed" or "must-have" budget. If I had to cancel one or the other, the travel goes, for sure.
