I know what you are saying. Last winter was odd for here, stayed around 30 degrees, I never put the snow blower on, we didn't have enough snow melt to sprout weeds to fill the ditches, was just odd. Bugs actually weren't bad this summer, but probably because it was so dry, usually a warm winter and the bugs get bad.
It was into the teens this morning, but temp is dropping fast durning the day, strong 20mph NW wind came up an hour ago, supposed to be 5 to 10 below again tonite.
With no snow cover, these cold temps are busting water pipes, see a street dug up in town once a week or so. If the cold is driving down that deep this year, should get rid of some of the corn bugs at least.
