If the Youth Groups open the Parks, and act as Hosts for the July Firework Season it may be the best of all worlds.
One, Designate a Zone or area in the park for Lighting Fireworks.
Two, Let the Teams sell in the Park
Three, Let the Teams sell Food and Water Mellon
Four, Have a Demonstration Game, or other Entertainment.. Perhaps just some good old fashioned 4th of July Music.
At parks there would be no drunkeness,
Open Spaces are Safer than around Homes.
If there were an emergency there would be sufficient number of responders.
Noise would be centeralized into one area of the city, any other areas under fire, would be clear, and more enforcable
The City of GT should Buy the Fire Department a Containment Container... to have on site of the Fire Department.
Just some after thought.
