Chris -
I was there a couple of times this year. First in June when I played 9 holes before a wedding, then 18 holes later in July. The first time I played we were rained off the course, so that was probably not the best time to judge the firm and fast fairways principle.
Perhaps it was the July heat, but when I played I thought it played firm, with drives getting a fair amount of roll. Nothing compared to what you are describing. While the rough wasn't short, it was hardly a wet 6", I would say more like a dry 3"?
Maybe it was the day I caught it, but I thought it played very well, hardly 18 perfect holes, but probably 6 realy cool holes, 6 good holes, and 6 P. Dye "template" holes. However for $40-$50 on a Saturday morning walking that is a fantastic value, for either locals or if driving down from Chicago.
