But I tend to get fuel at YLEC or YCBP before lobbing into YWMC. Trev makes more than enough out of us on the beers and the accommodation and landing fees. Jiggered if I'm going to pay $1.05 per litre premium for AVGAS as well!
In defense of Trev & other outback airstrips, I costs a fortune to get the truck up there. And the roads have been closed to 2WD trucks for some weeks and I think they still are.
I could see Coober Pedy to William Creek & back being a full day for a 2WD truck. All of that goes straight on the AVGAS price.
