Peters played for the Montana State Bobcats of Montana State College in 1924. He converted 17 drop kicks into field goals in a game between the Bobcats' freshman team and Billings Polytechnic Institute.[3][4] The Bobcats won the game by a score of 64–0.[5] The Bobcats helped him set up his drop kicks by falling short of the goal line instead of scoring.[5][6] Peters also made 15 drop kicks in a game once. Montana State athletic director Schubert Dyche said that "We agreed that every time we got inside the 30-yard line. Frosty would drop kick one."[7]
Peters spent time playing professional baseball in the 1930s.[3][14] He attended George Barr umpire school in Hot Springs, Arkansas.[18] He spent time as a baseball umpire, serving in the Florida State League and then the American Association (AA).[3][19] Peters's stint in the AA was interrupted by service in World War II.[3] He was a sergeant during World War II and spent time instructing trainees at an army air forces technical training command detachment at the University of Michigan.[20] He was assaulted by an AA manager in 1946. Peters then resigned, stating that "when an umpire gets socked and they fine the guy only $100 and five days, it's an open invitation for everybody in the league to start punching you around."[21]
