The answer is clearly Kankakee
Assuming you mean Kankakee Elks, why not throw in Spring Valley (Tigerman must be asleep or something). Both L&M, both bunkerless (SV) or nearly so (KE). I would call them surprisingly similar, but their similarities aren't really surprising. Some TLC, a big influx of money, a superintendent who knows what he has and what to do with it (Like Craig Moore is doing for the L&M nine in Marquette, MI) and each could be something close to Lawsonia especially with a fair amount of tree removal.
Spring Valley could be greatly enhanced
without a big influx of money. I'd start by expanding the greens to fill the existing green pads (maybe the single biggest need there), refurbish some tee boxes, do some prudent tree trimming (but not everywhere; the trees that narrow the great par 4 15th are intrinsic to making that hole stand out; the ones illogically planted on the short par 4 14th should be hacked down immediately), and even spiff up the flags and cups. The most expensive refurbish there would be adding the bunkers Langford designed for the course, but were never built. I'm not sure the course needs them; I'd put the other stuff first.
The folks at Spring Valley know what they have; their maintenance practices are better than a lot of the soggy stuff you see here in Wisconsin. Just not sure they have the money to do the above.
