Thunderhawk is a Lake County Forest Preserve course, and was designed by Robert Trent Jones Jr. and plays to 7136 yards, 136 slope from the back tees. It's located in Libertyville near the Wisconsin border off I-94, and is a great golf course. The layout is forgiving wide fairways with a few good solid risk/reward type holes through the forest, marsh and meadow design. Very well conditioned, nice tree lined fairways, Half the holes wander through open meadow while the other half are carved through the trees. Plenty of challenge with water hazards, fairway bunkers, and the wide fairways that narrow to areas bordered by the long grass rough. The bunkers guard the front and sides greenside, and the greens are mildly undulating and quick. Great course, a little expensive, probably neck and neck with Pine Meadows.
