Hillbilly Proud headed back to Newark, Ohio on July 13, 2013 for Brushy Fork Entertainment's Ohio Mudfest featuring Dennis Anderson and his mud truck King Sling and his son Ryan Anderson and his mud truck Son-uva Digger. The Mudfest grounds feature the competition mud pit, hill n hole, bounty hole, and an open pit area for the big trucks to play in. There were several big trucks to watch on this day, but the crowd was there to see monster truck legend and Grave Digger driver Dennis Anderson tear it up with his mud truck King Sling. He didn't disappoint as he ripped through all the competition pits and then put on a high flying freestyle show in the open pit area. Son Ryan and his truck Son-uva Digger made one good pass through the competition mud pit and broke. It had been a tough trip for the Anderson's mud trucks as King Sling had broke the week before in WV and during the Friday night preview show, but held together just fine for Saturday's show. It was a great day of mud slinging in Ohio and we greatly enjoyed watching the Anderson's awesome trucks.
