Well, it's not really seaweed. It's a combination of lake plants and
algae. We tried skinny dipping in it the first night. It was dark
and freaking scary. The time between clothes off, swimming and back
on the dock fully clothed was a little over 1 minute, lol.
It always feels like it is pulling you under and I can't help but
think snapping turtles, even though chris and (e:chris) say there aren't
any.

Where was this? This looks like the eutrophic Erie Lake.
