Hot, sticky and sweaty pretty much describes a typical August day in Chicago.   The airconditioner is broken, the kids are bored, the backyard is steamy, where can you get relief?  Pack your swimsuites and head over to the Crown Fountain in Millennium Park.  It's the coolest spot in Millennium Park.  Here you'll see kids of all ages keeping cool in the mists and sprays of the delightful Crown Fountain.  Giant faces smile down and occasionally spit fountains of water on people taking advantage of free, cool, refreshing entertainment.  This is one place where people are not only allowed, but encouraged to play in a public fountain.   If you don't feel like getting wet, it's a great place to people watch as mothers chase toddlers, kids play, and people of all ages keep cool on a hot summer's day.   If you want to be cool, head to Crown Fountain!
