Teens under 18 will no longer be allowed to party at Eight Great Tuesdays without an adult this summer. Erie Port Authorities have now imposed new restrictions. Starting July 10th, kids must be accompanied by a parent or guardian. This all stems from problems at the last four events in 2006. Officials say about 300 kids got into fights and caused problems for vendors. They say its now up to parents to look after their kids or they could go to jail. Kids with violations will be arrested for trespassing. Parents or guardians who don`t look after their kids during the concert could be arrested as well. Officials do plan to hold other events for kids this summer.
