Right now, my brain is fried trying to imagine how that original situation you described would work. I have even introduced magnets into the equation and still could not fathom the original idea. There is no way I could ever imagine that. I tried flipping the Earth on its Polar axis and that still did not work. That there is one dang big magnet I introduced into the calculations.
However, I would say that if that is what you originally thought, I would certainly understand how you could have your current concerns... along with living anywhere in any coastal state, whether west or east cost. I would suggest the mountains of Colorado.
For the record, the "Land Between the Lakes" is between Lake Barkley, formed by the Cumberland River flowing East to West and Kentucky Lake formed by the Tennessee River, also flowing East to West. Both rivers flow South and North at times. Such is most prevalent with the Tennessee River. Nevertheless, the two rivers begin in the eastern mountain region known as the Appalachian Mountains and flow westward toward the confluence of the Ohio and Mississippi rivers and regional drainage basin.
