Hood Park

I see this park shows out of season after Sept 6th 2022. As it averages 80 degrees in September there I am trying to figure out if its just FCFS after that, or actually closed as it implies on the site. I called the reservation line, that had no info and suggested I call the park. Of course the park number rings once and disconnects each time I try. It would seem odd to close that park when its still so warm there....
