I was just east of St. Louis for the T Day holiday. Gas prices ranged from $2.14 to $2.69 on the same day within a range of maybe five miles. The high price wasn't next to an interstate or major highway. The prices were within city limits but different little towns. I drove from St. Louis to Kansas City Monday. The cheapest gas I spotted was $2.05 in a couple places. This was within sight of I70. I don't remember the highest prices. There is a fence between the east bound and west bound lanes of I70 in Missouri. It's steel posts maybe three feet high with cables strung between them. It must've saved some lives over the weekend. There were maybe eighteen or twenty vehicles still in the median. It looked like more had already been towed.
