It seemed as though Cory was more than willing and able to drive his car harder than any of his competitors and could squeeze into spots on the track that most others couldn't. Cory's passion and desire to win led him to two NOSA victories. His first came on September 13th, 2013 at his hometrack, River Cities Speedway, with his other coming on July 18th, 2015 at Buffalo River Race Park in Glyndon, MN. Cory also picked up the Tyler Fedyk Memorial win at Nodak Speedway on September 6th, 2015.
In Cory's final two races, which came earlier this season, he raced to impressive finishes in both events finishing second on July 21st and third on July 22nd, right behind his older brother Casey.
The Northern Outlaw Sprint Association would like to extend their condolences to the entire Mack family. May Cory rest in peace and never be forgotten.
