My dad and I were fishing on lake Norfolk in the early 60's. I had a bite on the line just as my dad was firing up his lighter. Not being a very good fisherman, I jumped up to set the hook, and dad's Zippo went flying overboard. The lake water was high that year due to flooding, but the following year I could walk on dry ground in the same area we had fished. And up in the branches of a small tree I found the Zippo.
