Sunglasses caught on a log

We found these sunglasses caught on a log while we were walking down by the river! This is right after some of the heavy rains and the river was really full (and moving swiftly). I'd think someone lost them in the river somehow rather than someone was walking down by the river and set them down and forgot them. I say that because someone wearing these sunglasses wouldn't be the type of person I'd peg to walk through the foliage, down the embankment, and walk in the mud by the river!
