QUANTICO, VA — Last week, Interstate 95 in Virginia was shut down for nearly 50 miles due to massive snowstorms. Ron Hill, a truck driver from Maryland who was making a delivery for his client Schmidt Baking Co., was one of the people stuck in a long line of halted vehicles. He didn’t expect to spend nearly 24 hours in the shutdown, and certainly not to get caught in a whirlwind of national media attention for feeding the other cold and hungry travelers in the crisis.
