For your consideration ...
At Calvert Marina, Matt the owner, opens up his place once a year to the public to view the Solomons fireworks. Entering the grounds are signs that say loud and clear, in part, "NO FIREWORKS". Of course a feral lights off two mortars about 25 minutes apart, nonchalantly, after about 15 minutes, walks back to dispose of the evidence. Matt would've had the fella ejected and trespassed had he known about it. But no one, perhaps fortunately, else havoc might have ensued which would have ruined the evening for all, turned him in.
