your "distance" chart was discounted 30 years ago ... you need to factor in more criteria than "I'm far enough away" - simple refugee flow mapping quikly shows the fallacy ....

just as a quik example - your "spot" is equal 100 miles distance from two major cities - with the usual road web of interstate and secondary roads ... when the two cities refugees collide in between they begin their spread or midpoint encampment - 250,000+ unprepared and bare azzed sheeple don't bode well for you ....

and that doesn't include FEMA - if there's time for Fed involvement for city evacuation - your area could be the destination for 10,000s of Section 8 sheeple with their hands out - depending on FEMA - good luck ....
