I was with my family and some dinner guests at a local restaurant. After dinner we decided it would be nice to visit the park and to sit down and chat. When we arrived at the park there were several other visitors there. After about 15 min an officer drove up to the parking lot and alerted everyone that the park is now closed and that we need to leave. We proceed to our vehicles and as we pull out of the parking spot the officer circles back around and blocks us in (3 cars). He then cites us for staying after hours even though we tried to leave when he asked to do so. What should I do ?
