The two golf courses that put Wisconsin on the national golfing radar - Blackwolf Run and Whistling Straits - are celebrating anniversaries this year. Blackwolf Run, site of the 1998 and 2012 U.S. Women's Open turns 25. Whistling Straits, site of the 2004, 2010 and 2015 PGA Championships and 2020 Ryder Cup, along with the 2007 U.S. Senior Open, turns 15. It's been an amazing ride (so far) for Kohler.
