Squirtin Thunder ran up in his little 18 footer. I think the basin was the smoothest part of the lake on Saturday. I'd do it in my 21 if the water was like that. No probs. I think I have like 48 gallons. I would fill up at each stop. But that's just me. Especially cuz I have a jet and a big block. When I did the Avi to Havi run, I made it all the way and just had to fill up in Havi for the ride back. About 3/4 of a tank. Hoover is further though.
