After a year of celebrations in honor of their bicentennial, Colby College in Waterville had their final hurrah on Sunday. It was commencement day on Mayflower Hill.While graduation ceremonies had to be held inside because of the weather, it was still a memorable one.About 500 graduates from 33 states and 29 countries received degrees.”Well this has been an excellent class. They’re all pretty impressive, but I think particularly because this is the bicentennial class. It’s been a really outstanding one and its been a great pleasure getting to know them,” said President William “Bro” Adams. “To be able to go to school for four years in my home state and just get the incredible experience that I had at Colby and the incredible education, I couldn’t have asked for more,” said Rebecca London, a Carrabassett native. In honor of the college’s 200th anniversary, all of the honorary degrees were awarded to Colby alumni and the graduation speaker was 1973 grad Gregory White Smith.The Pulitzer Prize winning author said the speech was the hardest thing he has ever had to write.
