Zoomed in Ohio map has me at 6b, zip finder 6a, no change from prior years, the border runs right through town. but I went to use it since you mentioned yours changing and I typed in my zip and it asks for verification, which is such a weird thing. Sorry, we need you to prove you're a human being in order to use our zip to zone finder.
I mean, if you're going to put me through the indignity of a Turing Test you could at least pop out other data like rainfall data and standard soil type. I'm sure the USDA's Hardiness zone page is constantly under cyber-attack and going through a list that can't possibly be more than 99,999x2, with 5 digit and 2 digit cells definitely sucks up the processing power... bastards
