I remember here in Dallas it happened several years ago, took me six hours to drive home in a normal half-hour commute.
Yep, yesterday I left home in a small town area and it took almost fifteen minutes to drive about four miles. Very little traffic and what was there stayed far apart because the road was so slick with ice.
Some here who live where snow must be dealt with several months each year can't orient themselves to these southern snowstorms that come and go within one or two days, and are unpredictable as to how problematic they might be.
