A Little Excitement In My Neighbourhood

For the past few nights there have been a cadre of 2 or 3 teenagers going through my back alley. Other than being louder than was appreciated, they seemed harmless. But this evening, around 11pm they started firing off firecrackers and then fireworks. But the little jerks shot off the latter into some nearby trees. And in no time at all these trees burst into flame. The arsonists, accidental or not, took off of course, but my neighbour and I are now on the lookout for them, as are the police.
