What makes you think it's ok mr. entertainment to conduct your cheesy pyroclastic carnival on public property and not pick up your leavings when you are finished?
To wit:

18 final stage rocket husks, these smell really bad!
sidewalk colorings, looks very shitty now
untold number of matches and 1 discarded bic lighter (rusty maybe it wasn't yours)
3 stacked coors light silver bullet cans
2 boxes of confetti saw dust crap that housed your rocket splendor i suppose. These are wooden and kinda ornamental. keeping them for crafts.

With no rain on the horizon i gotta know when you are cleaning this up?
