Owned parks for years. When dealing with the public you will quickly learn they will parse the English language to justify doing what they want to do. They say their dogs are poodle mixes when they are very obviously pit bulls and Rottweilers . Those 2x4s and pallets might be insect free but they are scraps from a demolition crew full of nails, with pieces of drywall and asphalt shingles still attached. The burning shingles provide the wonderful ambiance of dark black acrid smoke. The drywall doesn’t burn at all and the nails eventually find their way into a tire or foot. Too many people have the mistaken belief if it doesn’t say you can’t do something it means you can.
