This park is not set up for this type of event except once per year. Normally it's a place to go for a family picnic or set up a volleyball net. Grassy with sycamore trees.
For Garlic Festival, they surround the place with rented chain link fence panels (maybe 8 feet square?) chained together. Entrants are funneled through a quick pass through the metal detector.
Plenty of cops there. I worked at least once as Mounted Sheriff Posse (non-LEO) riding the inside perimeter to report potential problems and provide a visible presence.
Any bolt cutter can get through the chain link. Then this guy had to find a quiet corner where he wouldn't be seen cutting the fence... not hard as the park borders wild areas in the back.
Regardless of the reason that’s ginned up, we all know what the only solution will be.
You know, the solution that has never worked and never will work.
