Liquor stores hate them.  Car sales people love them.  'Blue Laws' are laws used to govern certain moral standards, and are usually in reference to laws prohibiting actions on Sunday.  Most of these 'Blue Laws' around the country have been overturned, declared unconstitutional, or are left unenforced.  Minnesota is one of the few states which prohibit the sale of liquor on Sundays, except for 3.2 beer.  Try buying a car in Minnesota on a Sunday and you'll be out of luck.  Employees love the day off, and are fearful of the day when you can buy are car any day of the week.  There is now a bill, H.F. 3681,  with bipartisan support to remove these prohibitions against operating businesses on Sunday by Rep. Phyllis Kahn, DFL-Minneapolis, and co-authored by Rep. Chris DeLaForest, R-Andover.  Kahn doesn't believe the bill will get out of committee, but is there, "to let people know these silly laws exist."  I, for one, would rather get rid of silly laws.  If you support the bill, contact your state representative.  You can read more at Minnesota Monitor.
