Yesterday I finished a three week tour thru north Georgia, Alabama, and then the Natchez Trace through Mississippi down to Meridian. I've noticed that there is at least one Subway restaurant even in very rural areas where you might find almost nothing. They don't always pop out of nowhere but a google maps search almost always finds something nearby. As I browse the US in general, they seem to be almost anywhere one might go.

This makes for a real easy eating plan. I carry oatmeal, dried fruit, and some soy milk for breakfast. Then stop at subway and eat half a foot long and a couple cookies and pack the rest with me for supper. All food groups. Easy prep. Pretty affordable.
