Find a safe rope tied to a tree, over a lake that is deep. A spot where you can’t touch the bottom when you jump in. No rocks or branches sticking out anywhere from the tree or the lake. A place, completely safe is a good thing. The rope, tied tight by someone who knows how.
Or find one that is tied safely, by someone nice who left it for everyone to use up at the lake. Get the rope (with a paddle maybe.) Hold on tight. Smile.
