An 18-wheeler engine fire at the Circle K truck stop parking lot torched another parked next to it Wednesday around noon. Guests from Smolik’s Smokehouse highway location could see the flames from the windows and were urged to stay back as owner Gail Smolik was afraid the engine might actually explode. Mathis Volunteer Fire Department quickly arrived and doused the blaze though not before the cab compartment was completely destroyed. No one was reported to have been injured.
