The Mosaic District hosted its annual “Bootique Trick-or-Treating Spooktacular” event on Wed., Oct. 30 in celebration of Halloween. Hundreds of whimsically costumed children walked store to store to fill up on sweets and treats. The film “Monsters, Inc.” played on the “screen on the green” to top off the fun-filled evening. Other venues such as Fair Oaks Mall, Tysons Corner Mall and indoor play spaces also hosted trick-or-treating events, giving shelter from the rainy weather.
