TODAY IS NATIONAL MUSTARD DAY and it's the biggest day of the year in Middleton,Wisconsin which is home to the Mustard Museum.  I wish I was there today because they have a line-up of events that sound like a whole lot of fun.  Get all the information right here.  The festivities get underway at 9:30 with the POUPON U ACCORDION BAND and that, alone, would be enough to entice me to spend the day in Middleton!
