What about the dam drop on the Ark fractions/narrows section? A woman died there a couple of seasons ago on a commercial trip I believe, and there may have been another accident there in the past few years. It could be a hypothetical portage with a fatality to back it up, and I think it has private property on both sides.
If you search mountainbuzz, I know there are pictures on here somewhere.
It takes a big man to cry...It takes an even bigger man to laugh at that man.
