I think I found the cheapest airplane fuel in the entire world!! After a tip from a pilot friend, Karla and I fly my AG5B Grumman Tiger from Los Angeles to Inyokern, California to get the lowest price AvGas I have ever seen!!! I guess that makes it the cheapest AvGas in the entire universe!! If you know of any 100LL that is any cheaper, I want to know about it.
Inyokern is a small airport in the Mojave desert along the easter slope of the Sierra Nevada. it's a popular location for gliding and soaring due to the mountain wave activity. One of my favorite things about general aviation is visiting these small out of the way airports that I would normally never go to.
