Spread the spirit of Halloween with this Fall take on Secret Santa! Share treats and signs with neighbors to start a new trick-or-treating trend. Here are the rules of BOO-ing for your instructions to include: 1. Wish the BOO-ee a Happy Halloween and to enjoy the treats. 2. The BOO-ee must place the “We’ve been BOO-ed” sign by the front door. 3. The BOO-ee has 72 hours to leave a BOO sign, instructions and treats at two other houses. Have fun!
