Steve, for better or worse, they were/are one of the few courses that charged raters to play. They didn't want to comp anyone, for whatever reason.
We were on a Michigan junket in 2008 when we played, and we took the first twilight (2 pm) round available; it cut the freight in half, to $100.
I recall that diner up the road that seated you and took your order in 5 minutes, then took 75 minutes to deliver the food. We almost missed our tee time.
