Out west you need a fuel cart to take gas to your car from the airport rather than the other way around...haha
I get 100LL at Sherman (KSWI) any time I can. $3.65/gal. Of course I filled up my truck yesterday at Kroger for $1.83 (with my discount points).
...100LL costs $4.15/gal and 91 octane 'premium' is $4.599/gal.
Please have mercy on those of us who live in a state that thinks a special gasoline is needed and we are all rich so price is not important.
I am so glad avgas is the same throughout the nation.
