Ken,
I'm amazed the a fine (hand muffled "bulshit") upstanding (hand muffled "dbl bulshit") organization like ACG woudl allow such behavior. Years ago, we were playing one of their courses up and experienced what you did. After complaining to a marshall for abou 10 holes, we sat on the 13th tee waiting for the golfers on the who were playing the U.S. Open, line up and putt out for TEN minutes. The marshall was shocked at the time they took on the hole assured us he would take care of it. He proceeded to pull a u-turn and drove away in the opposite direction!
Sad truth is that it's not just AGC. There are certain courses (a majority) in our area that we don't even waste time thinking about playing. The fact that they are a majority proves your point. Unfortunately, most courses just don't care enough to enforce pace of play. Truth is that they would probably improve their business as serious golfers would flock there if they could play in 4-41/2 hours.
Let's work on something easier like peace in the middle east!
Good Luck!
