Wow... looks like this thread touched a nerve with some folks. Based on the locations of some of the posters it may be that certain colder regions of the country have moved to a 'jeans acceptable' policy. Maybe its a NW thing... to each his own.
Thats not the case here in VA. Its a pain to change before a round but the rules help keep a standard in place. Besides, it gets too damn hot here to wear jeans. That being said, put me down as one of the preppy fratboys. I like to look good on the course and in the bar afterward.
Now if only my game were that easy to put together.
