As we all know now, inflating tires can save America 3% in gas consumption. I have a very simple idea which I think the Obama campaign could easily implement, which would garner a lot of publicity... why not station Obama campaign volunteers in parking lots with air compressors and Obama tire guages, and actually volunteer to inflate people's tires? This would give a chance to spread the word about Obama, it would be a great service to the community, and it would actually begin the process of saving energy, here and now. The tire pressure guages would be available for a small donation, along with bumper stickers and free literature.
