Patrick Dempsey hit the road in Maine over the weekend for a two-day philanthropic ride to raise money for his Center for Cancer Hope and Healing in his hometown of Lewiston. An avid cyclist, Patrick was joined by more than 1,800 other bikers for the trip, which raised $1.1 million for their cause. Like many other stars standing up to the disease, Patrick has long been passionate about his mission. He's also committed to his role as McDreamy on Grey's Anatomy, and the new season of his series is so far full of the drama we've come to expect.
