Jan. 17 – On this day in Montana history in 1972 members of the Montana Constitutional Convention gathering in Helena were urged by Convention President Leo Graybill Jr. “to look ahead 70 years when rewriting Montana’s 1889 Constitution.” Perhaps harkening to singer Bob Dylan’s popular song of the day, “The Times They Are A Changing,” Graybill said: “The central truth of our time is change – constant accelerating change.”
