128-year-old amusement park tightens its rules after violent teen takeovers hit rivals

Kennywood, a 128-year-old amusement park in Pennsylvania, has tightened its summer chaperon policy, requiring guests 15 and under to be accompanied by a supervising adult from June 12 to Sept. 7. The change follows violent teen-related incidents at other parks, including Six Flags St. Louis and Hersheypark, which involved large-scale brawls and police interventions.
