This fall I was in Iowa and had to pick up a coworker at the airport in Des Moines. I was sitting in the cellphone lot and as the sun started to set this crazy noise started picking up. It sounded like it was almost... spinning in a circle around the airport. The direction seemed to be constantly moving. For a while I thought it was one of those noise generators that were meant to annoy teenagers. We got back to Ames and I started hearing the same noise in the hotel parking lot. I have no idea what compelled me to think "cicadas" but as soon as I googled it I confirmed that that's what it was. Crazy crazy little creatures! Had a similar experience around dusk earlier this year when I started thinking that I was having vision problems. I kept seeing all of these weird little sparkles of light out in a corn field. Sure enough, fireflies!
