Russell,
Knowing how to play your home course simply means "you know how to play your home course". I'm not sure it translates into understanding and/or appreciating golf course architecture. In my humble opinion, there is no better substitute to learning about golf course architecture then playing and studying lots and lots of different courses (good ones and no so good ones). The other thing that helps is to play with members of those clubs (who know the course), and if you can, play with the architects of those courses. It's amazing what you can learn!
By the way, Mauna Kea was designed by RTJ Senior I believe! I really enjoy that golf course!
