Ruckersville, VA. – Matthew Peterson and co-driver Bryce Marshall drove the Mad Matz Unique Jeepz 500hp “Screaming Green Machine” to a respectable 10th place finish out of a very competitive field of 31 vehicles at Badlands Off Road Park in Attica Indiana this past weekend. The race began with a field of 31 specialized desert racing rock crawlers from the east and west coasts, with only 17 finishing this grueling Ultra 4 Race Series eastern series qualifier for the 2014 King of the Hammers.
