Get ready to "Grow Your Hear 3 Sizes" as The Grinch returns to Naperville in 2017! Find The Grinch! He is hiding out at several Naperville businesses this holiday season. Get your participation sheet and a list of "clues" (participating retailers) from Anderson Book Shop. When you spot The Grinch in Naperville, ask the store to stamp your participation sheet. How many stamps will you get for spotting the Grinch? There will be a Grinch Party to wrap up this seasons long event at Anderson's at 11AM on December 29th. We hear there may be a very green special guest making an appearance!
