Need to save money on Gas?

Are you like me where you constantly watch the gas prices and try to be strategic with gasing up on the right day to get the cheapest price?  I want to save that extra penny or 2.  My mom told me about a gas station next to Marina Point (literally off the Ohio River) and in front of the LST boat.  This gas station I believe is geographically in Kentucky so it has Kentucky low tax prices.  On Sunday gas was $3.18 there.  I was able to gas up on Tuesday and it was $3.34.  Just wanted to pass this on for anyone who could use some cheaper gas.
