I still maintain that I have never seen a boat on that water, not in 39 years. That doesn't mean that they don't occasionally bring some in for special purposes. IMO, a boat would be remembered because they are rare there. In addition, the water would have taken him further out into the open past businesses, busy roads, and people which would've made him more conspicuous. I do not have a link to provide, just personal knowledge of the actual creek in question.
