I’m sure it was a beautiful July night on the banks of the Mississippi. Your group apparently drank lots of beer and hard liquor, and shot off some sizable fireworks. This is the scene I just had to clean up as I hiked along the river this morning. I suppose the drinking and the fireworks were illegal, but what takes my breath away is the selfishness in leaving a big mess for the rest of us.
