Hmm I also think there are different strokes for different folks as Bob pointed out one thing. These are things I would try to do. I like to play with a staff member or club historian etc. If not then ask the Director of Golf questions about the course such as types of grasses, drainage,, original architect, changes, when and who did them, things about the course routing, holes, interesting shots that exist and other historical facts of interest. I like see course in a cart so I can look at different shot angles and tees which might be missed walking the course. also make sure to look at each hole backwards to get impressions that for me would only come from playing a course many times. Obvious;y as Mike pointed out, an appreciative humble attitude with good manners and making a point to understand local rules and policies are important.
