Well i can tell you for a fact that anything below grayling in michigan is screwed. Saginaw had 3 pointed at it.. midland had 3 .. bay city had 1 .. detroit over 10 ( covering suburbs as well .. flint 4 or 5.. battle creek, kalamazoo.. grand rapids, ann arbor, Lansing, Muskegon, Alpena, Oscoda ( wurtsmith air force base)
these cities would all be toast as they were prime manufacturing cities during these periods. Midland would be toast just for Dow...
Saginaw boasted several foundries during that time frame, plus Saginaw Stearing Gear. and several assembly plants. Flint had bus and truck.. Buick City. The whole darn automotive industry ran from Saginaw down to Detroit..
In Wisconsin.. many of the cities bordering the lake would also get nailed running from green bay to chicago. and around to grand rapids up to muskegon. .. toledo, cleveland, ashtabula, erie, PA
