Stephen,
I think you would be surprised how many people and places will open doors for you if you are genuine in your desire to experience great architecture and courses. I'm not sure how Mac meant his belt-notcher comment, but I really think most people who want to see great courses do so because its an interest or a passion for them. Most of my friends are NOT impressed by the courses I've played and think I'm nuts for traveling around to see golf courses--but they don't play golf (much) anyway.
I guess my point is that I'm currently a financial aid officer in New Mexico, originally from Indiana. Ten years ago I had played about two courses of any real architectural significance and had no real reason to think I'd ever see the greats and honestly had not really given much thought to it. My interest came from playing mainly public courses (Whistling Straits, Blackwolf Run, Arcadia Bluffs, Harbour Town, Tullymore) and it grew from there. Admittedly much of my access since then has come from joining a magazine rating panel, but I've also been invited to play Pine Valley, Shinnecock Hills, Cypress Point, and Crystal Downs through the generosity of friends. PV and CPC were two of my four original "dream" courses along with Pebble (which I've played) and Augusta (which I haven't). I'll consider myself very lucky at 75% of that dream. The friend who invited me to Pine Valley had played it many times and gave up his spot in a foursome to let me play--he walked with us and took photos. I wish I had the ability to "repay" those friends with more than gratitude and some small token of appreciation, but given that its Thanksgiving tomorrow I'll suggest that sincere gratitude is a gift too. I've had a few chances to help others access places they could not have seen otherwise, so I hope that I've done something worthwhile by paying it forward, so to speak.
