A lucky key made Brad Peterson of Wellington, CO, the grand prize winner of the “Drive a Firestone” sweepstakes organized by Bridgestone Commercial Solutions. Peterson took home a 2013 Firestone Edition Class 8 Peterbilt tractor, an all-expenses paid trip for two to the 2014 Indianapolis 500 race, assistance to help defray tax costs and up to a five year supply of Firestone tires.
