Atlanta is a dirty city I don't know how dirty but I do know.
Almost any major city is dirty just look at the picture but of course the anti GW people will say its only a dirty camera lense.
"Those who do not learn from history and condemned to relive it".
"There are those who will debate the necessity of wilderness, I will not, either you know it in your bones or you are very very old". Aldo Leopold - Sand County Almanac
