I keep my boat at Fenwick and fuel up on the way in after each trip at Turtle Point. Have never had more than one boat ahead of me getting fuel. Key is to get filled up coming in, not going out in the morning. They advertise no ethanol in their fuel. Not sure about Wild Wings. A call to them would give you the answer.
Also believe they have ethanol free fuel at Anchor Point. If you belong to Boats US I think they have listings on their website.

Good fishing,
Gill
