I saw some news reports on the teevee last night which indicated parts of Chicago and its outlying suburbs are finally starting to see cicadas emerging.
You may want to consider checking out some online maps devoted to showing cicada hotspots.

Unfortunately, these maps are reporting just on stuff entered by people online.
What would be really cool is if cicadas excreted some unique set of chemicals that could then be sensed by some satellite and then there could be detailed, accurate maps of the bugs, and, and, and, and we could all be wearing hoverpacks, flying over the cicada parks and then, and then cicadas would launch at you but you’d have your anti-bug laser pistol handy and…. oh well.
Hide out down here in Georgia. We’re cool — bug-wise and humidity-wise — so far this spring.
I think I found a cicada in the school today. If so, I may recover from Brookfield hoggin all the cicadas.
My brother was just out at Carpenter Park (near Springfield, IL for you Northerners) and he said that there were “lots” there and even that one was friendly!
