Kevin Wentz, of Loveland, Colo., fuels his truck Friday at Flying J in Rapid City. Wentz said the winter weather added about an hour to his trip from Loveland to Rapid City overnight Thursday. After a break for sleep, he was scheduled to depart for Loveland at 1 a.m. Saturday. Wentz said if Interstate 90 was still closed then, he'd just wait it out. "I'm used to it," he said. He has driven for Food Services of America for six years.
