October weekends mean fall-themed fun at Luna Park, normally a summery destination. Kids can guess the weight of an enormous pumpkin for the chance to win up to $1,000 (Sept 20–Oct 26), and then watch it get carved by master Marc Maniac on October 26. Costumed characters will roam the park, where kids can also embark on a scavenger hunt and practice their trick-or-treating skills with free sweets from Welch's Fruit Snacks (10/12, 10/19, 10/26). And of course, there'll be rides a-plenty. All ages.
