All-Out-Call-Out is an event that really likes to shake things up down in the desert! Each racer in each class is subject to the same roll of the dice as the other, by either being able to call out or be called out by another driver! It’s a game of Russian roulette as you may not have any clue who you’re being challenged by, or who you may be challenging. New Mexico comes prepared with a wide variety of radical street cars while neighboring states like Utah and Colorado make the trek down to represent what they’ve got! AOCO is easily one of our favorite events of the year, and one we don’t intend to miss!
