We have reached the time of year when someone in the neighborhood sets off *one* firework late at night, then waits an hour or so to make sure that no one’s called the cops, then sets off another one, then repeats the process every night until a week or so after July 4.
At least here, it happens every June. Also about a week around New Year’s. I’m pretty sure that someone in one of the nearby blocks stocks up on fireworks every July and saves part of the stash for the following June.
