Most smaller airports will sell you small quantities of AvGas with a walk up container. I have bought at 5 different airports and have only been refused once. The one that refused me was the largest, but still pretty small, they said it was a restriction put on by their supplier. The airport I use now, the fellow even helps me carry the gas back to my truck. I usually get 15-17 gallons each trip, usually ever couple years unless there is a long power outage. I keep it in a shed with my corn free gas, I don't like keeping gas in the garage. I re-read my message above and called it 100LE was suppose to be 100LL it is 100 octane low lead. Before someone brings it up you can use higher octane than you need just not lower, runs fine. For us older folks it smells like gas did in the 60s and early 70s before they started messing with it.
