Location matters, and not just for real estate sales.
Folks in St. Clair Shores and the Grosse Pointes swat and sweep lots of pesky mayflies in late June and early July, but can be thankful they're on Lake St. Clair rather than Lake Erie.
Seasonal swarms of the non-biting insects also called fish flies are so massive in northern Ohio they appear on Doppler radar, as well as in crunchy piles on streets, sidewalks, yards, benches, parking lots and vehicles.
There's a welcome side, too: This year's unusually large hatchings -- which number in the billions -- indicate good water health and low pollution in the Great Lakes, scientists say.
Behold recent scenes:
