Smog

A pretty picture with the moon in it that has a dark band of smog running just 100 feet over the road drifting in from Mexico. It was like a charcoal gossamer veil drifting north with the prevailing winds. We have a free trade agreement with this nation but nothing that curbs there emissions or burning of garbage which contributes greatly to the Southern California smog problem. (After seeing this, that is my conclusion)
