I love this sign, posted near one of the pieces of rapids where people are least likely to swim. What is there, 3 or 4 inches of water here? I snapped this photo at Kent Falls State Park in NW Connecticut. The sign is posted not too far from places where water does pool in such a way that you could imagine people swimming, hence I wondered if they could have found a better spot to nail up their warning.
All in all, I think the rocks at the bottom left of the image are my favorite part of this photo!
