We have Cicadas here in the woods of GA and there are times when you're sitting out on the porch and can't even hear yourself think

In the beginning of the spring you can hear what I swear sounds like swarms of them "approaching" as they are off in the distance and get louder every night. Sometimes you can hear them in the morning, but rarely. They are odd things - huge and very clumsy. I've had a few get into the house through an open door and thankfully they're big, loud and easy to find to herd back outside
I live in an area with very little deforestation and little disturbing of the ground, so whatever was there 17 years ago, should still be there.
When I looked on the map, my town was on the far west edge of where the worst of this 17 year swarm. I think it was supposed to start today? So far, just the normal really, really loud sounds, but we'll see.
