When author and photographer Gayle Harper learned that it takes 90 days for a raindrop to travel from the Mississippi River’s headwaters to the Gulf of Mexico, she knew she had a new project: Follow the path of that raindrop.
That path became a book, “Roadtrip with a Raindrop: 90 Days Along the Mississippi,” full of photos and a series of vignettes. Along the way, Harper said she found that there’s something special about life on the river.
