On Monday, WCCO-AM (Minnesota) radio legend Roger Erickson died at the age of 89. Erickson began working in radio in 1959. One of the many things he was known for was his 5 a.m. program giving morning warnings, telling everyone that their school was closed. He was also part of the Boone and Erickson show for 37 years. Erickson retired in 1998 and was inducted into the broadcasting hall of fame in 2001.
