Reflections of Granite Lake

Granite Lake in the Powell River back country is a favourite destination for a quad ride. Our last trip was in October when the sun was brighter and the leaves were turning,

There's an island in the middle of the lake. It looks like a beautiful spot to take a kayak or canoe. As we sat on the shore, our good friend John told us this story.

Hey Wayne and Margy, see that island? One time Eldon and I rode our quads out there. It's a beautiful island to explore. Can you figure out how we did it?

Wayne and I tried to figure it out. My guess was that they got a running start and the air in the tires on their quads gave them enough flotation. (OK, that was an airhead answer). Wayne thought maybe they had a raft stashed somewhere along the shore. That was more reasonable. People have made rafts for similar purposes on other lakes. We never did come up with the answer until John told us. Can you? -- Margy

p.s. Here's a hint.
