I don't think that Bollingbrook is that bad. Granted, it has a lot of water in preposterous places but it is an enjoyable course to play. When playing a Bolingbrook Munie built in the middle of the cornfield, what else can be expected?
Butterfield is a great place! I didn't think the course was very difficult but I had a blast playing it.
And Terry is right. By most accounts, Butterfield has a 7 year wait list that is arbitrary in its progression. Moreover, the Hinsdale, Oak Brook, Western Springs and LaGrange area has lot of significant wage-earners as residents.
As such, I don't think it will have any problem raising the dough.
