Just did a Map Quest look. From my residence, near Montgomery, AL, I can hit Carter, Clinton, Bush (elder), Bush (junior), LBJ and home in 2042 miles. And I do not have a SS2000 cert! One question I'd have is how close can I get at night to photo/Spotwalla my visit. Street view might help. Sketchy areas for gas? Fences and signs? Say I DO have an IBA flag....
