Rock River HOG Chapter’s Ridin’ to a Cure Every year, on the last Saturday of September, the Rock River HOG Chapter of Oconomowoc WI, hosts a fund raiser motorcycle ride for breast cancer research. This ride is called Ridin’ to a Cure. On September 29th, 2007 the 13th annual Ridin' to a Cure event raised $295,000 with over 2100 participants. Each year, the Medical College of Wisconsin Cancer Center has the opportunity to apply for a portion of these funds for basic science research projects.
