Buying/selling automobiles (dealership) on Sunday is another.Seems to me when I came to live in Indiana in 1987, there were a number of things that couldn't be sold in Indiana on Sundays. It's a holdover from a time when the family worked six days and, even on farms, the Sabbath was reserved for church activities and rest. Such "blue laws" were not unknown in the southern states when I was passing through (military training at various bases) in the 70's. As I remember it, Louisiana had Parishes (county equivalents) where this was so, as did East Texas and Alabama. As it is here, the pressures to keep the bans in place were traditional and financial, and the pressures to overturn the bans were mainly financial.
In fact, I remember a time when you could not legally purchase Coors beer East of the Mississippi river.
