Ervin Carlson was born on March 20, 1918, at Mackay, Idaho. He first began entering rodeos in the 1940’s, competing in the team roping and calf roping events.
Calf roping remained his true love throughout his rodeo lifetime. He also had a love for training horses for calf roping.
In 1960, Ervin and his wife, May, now deceased, moved to Vaughn, Montana, where Ervin still lives.
They raised one son, Blaine. Erv and May built an indoor arena at their residence outside of Vaughn in 1970 and spent many years putting on calf roping and team roping events at their arena until the late 1990’s.
