Lowest Fuel Price you have ever paid?

For my B $ S engine I used to run on the lawn on a stand I built (I was 10 and the go kart was still being built) was 49.9 in 1974. My neighbors really thought I was nuts !! LOL!! They finally complained enough that I rigged up the garden hose to the exhaust to quiet it down .... you ever hear the term "just smart enough to be dangerous" ?? Dad used to mutter it all the time LOL!!!!
