I have been warned that "Brood X" is coming. The news pundits have done their jobs.
I poked around Google and even downloaded "Cicada Safari" (available for Android and iPhone) thinking this event will be interesting but probably annoying for the most part.
Brood X is a particular group (if you call billions a group) of insects known as Cicadas. There are a few different broods, but this happens to be the one causing all the fuss.
