Illustrative image: A bunch of us went tubing down the Delaware River. It's pretty simple - they drive you upriver a bit, and you spend four hours floating back. A good way to cool off on a hot June day. And also a good way to get the worst sunburn of your life (which I did, but Sue got it even worse...) — Joe Shlabotnik/Wikimedia Commons, CC BY 2.0
