Today's date is 7-11-14.  The 11th day of July every year is when the '7-11' convenience chain celebrates their customers by giving away free small Slurpees from 11AM to 7PM.  The only 7-11 in  Greater Lansing that I'm aware of is at the corner of Jolly and Okemos roads in Okemos. The Detroit Free Press has the story here of how the Slurpee came into existence.
