For anybody who wants to work on, play on, visit, or live near, any of these bodies of water or their beachs, fagetaboutit.
This will be more strictly enforced than our borders.
When speaking of the great lakes (or any other body of water) its best to understand that they generally mean the entire watershed. I live on the interior of Michigan and I'm supposed to get approval from the Army Corps of Engineers to put in a permenant dock at the little lake I live on.
They don't want their control to end at the shorelines, they intend their control to go all the way to the groundwater under the land. For a water state like Michigan, it would mean getting rid of pretty much every last one of us. Personally I'm not so sure many of our economic problems aren't deliberate and rooted in the idea of evacuating us.
