That's a good point, and may well be the rationale.
I have a friend leaving from Dothan, AL and going to Biloxi, MS in the morning. She is taking a motor home loaded with five generators, chain saws, water, and other necessities to folks in Biloxi who are in bad health, yet fortunately, have survived with their homes intact. She has asked for a passable route. I saw some links yesterday, but I can't locate them from the incredible volume of posts on these threads. Could anyone please provide me with a link to the resources with this information? Thank you ever so much.
