A Boo Basket is a Halloween-themed gift basket that is left on the doorstep of a friend or neighbor to surprise them. The idea is that the recipient will "pay it forward" and will, in turn, create another Halloween Boo Basket and gift it to another neighbor. Its a bit like Secret Santa, only scarier! The basket can be filled with Halloween-themed treats, such as candy, cookies, caramel popcorn, Halloween toys, coloring books, crayons, glow sticks, play dough, puzzles, and balloons. Boo baskets can also be customized for adults and can include items like blankets, candles, beauty products, books, and even booze. The fun in the Boo Basket tradition is the mystery of the giver, but with most homes having front door surveillance these days, it might be hard to keep your identity a secret. Nonetheless, its worth a try!
