I’m among those who don’t favor clowns – not pathological about them, but outside of Bozo…ugh.  Admission for one or two to Haunted House and Fear Factory 3-D at Massacre Haunted House in Naperville (43% off).  Horrors lurk through 60 rooms housed inside a more than 15,000 sq. ft. haunted house littered with mazes and animatronics.  Limit five Groupons per person.
