I had to get gas this morning, and I've never had to wait before. There was a six car line at the station I went to. Luckily, it moved quickly. Apparently, it was much worse yesterday. Arizona gets all its gasoline from California and Texas, and a few weeks ago, the pipeline from Tucson to Phoenix burst. So since then they've been trucking gas in from Tucson. That means gas stations have been getting fewer shipments, and they haven't been able to keep up with demand. More demand than supply. Well, yesterday demand finally exceeded supply. Until they get that pipeline fixed (no thanks to the government and their inefficient regulatory process) there might be a slight gas shortage.
