Steve, you must be from heartier stock or in a more temperate climate or both to sleep with windows open all year! I turn the temp down at night, but weeks on end of nights below freezing are hard enough on my central heating with the windows CLOSED. Might be more common in house without central heating? The only hearty sleep-in-the-cold person I've encountered in person was Margaret MacArthur, who repaired to her van to avoid the warm.

No cicadas in Cleveland so far. I can recall large numbers in previous cycles, but nary a one in Northern Ohio that I've heard.

Joanne in Cleveland, headed off to the first outdoor festival of the year ( where I'm not camping because last time I froze)
