Though its right in the middle of one of the finest golfing districts in the world, Lake Isle is not in the first or second tier of courses and is much closer to a municipal track in reputation than anything.
Formerly called "Vernon Hills" (up to the early 70s?), it is short, tight, and heavily-treed, with OB left on almost half of the holes and three holes which play along the perimeter of a strip mall/shopping plaza. For a "private" club (I did not know it was still fully private) it has an indifferent level of turf maintenance and very uniform oval greens throughout.
I haven't played there in more than a dozen, fifteen years, but it is not exceptionally fun to play from those distant memories.
But any day out on the links at a new place should be fun; and so please enjoy yourself...but do not expect to be blown away by a hidden gem.
cheers
