Where did the term "skid row" come from?

Skid row originated from skid road, which was a forest track over which logs were dragged to get to either water for transport or the mill. By 1915, skid road had come to be used to indicate a street or area of cheap shops and resorts, a relatively disreputable district. By 1931, the term had become skid row and was used for areas where derelicts and hoboes hung out.
