Around here it's Cicada season. They're HUGE and they're scary looking, and they are LOUD, especially in the evening. But they're harmless.
These were around NJ this summer, but only in certain areas. My bro-in-law had a graduation party for my niece. As I drove my aging Dodge Caravan towards their house, I thought I heard a sucking sound, as if I had a vacuum leak. As I got closer to their house it got louder and all I could think was I'd get there and wouldn't be stranded. I pulled up outside their house and went to open my hood. My nephew ran out and told me it wasn't my car, but the Cicadas! Sure enough, once I turned the car off, the sound was overwhelming. It sounded like an enormous gas leak. So bad that they had the party inside the house with all the windows closed! Man those cicadas were loud.
