Corrected entry: The sheriff is transported out to Quik Phil's, and determines to return to the town. It is later established that the truck stop is 25-27 miles out of town, yet Sheriff Dutton manages to return, on foot, despite roadblocks and armed military, within hours.

Correction: A person walking at a brisk pace averages 4 mph. To go 25 miles would take about 6.5 hours. The truck stop would be 25 to 27 miles along the main road. Being the sheriff, he would likely know shorter overland routes or shortcuts to avoid roadblocks. Jogging, or walking faster would take less time.

The sheriff may have found a bicycle along the way or any kind of conveyance. Nothing in the movie implied that he walked the entire way.
