Gas Prices

What I find the most annoying at the pump is fluctuations from day to day. This morning one station was $0.20 higher across the street from another on my way to work. What I think we need is a statewide gas price to reduce the volatility at the pumps. It is ridiculous to have the prices go up or down $0.20 in one day or if you drive 5 miles down the road.
