Halloween is particularly strict in Delaware. To prevent mischievous actions by youngsters on October 31, children can only go trick-or-treating between 6 and 8 p.m. Oh, and if the 31st falls on a Sunday, the trick-or-treating will take place the night before, also from 6 to 8 p.m. Hopefully the earlier hours means families will show up in adorable family costumes!
