+1 for Nigel's mention of Kankakee Elks. I played there last Friday with some folks from my semi-regular Saturday game. $20 including a cart is their regular rate on Mondays and Fridays, and there's a coupon in one of those Chicagoland golf magazines for that same rate the rest of the week. Not the longest course out there, but a bunch of stout par 4s, mixed in with some cool short ones, and the set of par-3s is nothing short of fabulous. Greens were firm, quick if not lightning fast, and undulating. Short side misses were death. Can't wait to go back down there.
