Friday, October 30, is Arnold’s annual Halloween carnival! Kids of all ages can enjoy trick or treating at downtown businesses, enter the Best Decorated Pumpkin Contest, try out their Halloween costume in the Kids Costume Contest, and play games at the Arnold Community Center. But it’s not just for kids! Adults can also participate in the Best Dressed Pumpkin Contest, Best Dressed Adult Contest, or the coveted Best Themed Family or Group Contest. It’s good fun for all ages. The fun starts at 9 a.m.
