When Gayle Harper learned that a raindrop falling into the headwaters of the Mississippi would travel the river for 90 days to reach the Gulf of Mexico, she knew immediately that her project of a lifetime had appeared.

Harper made a 90-day road trip along the nearly 2,400-mile course of the Mississippi, while keeping pace with a raindrop called “Serendipity.”

She wandered back roads without plan, meeting people in farm fields, on their porches, in cafes, even while stopped for road construction, who invited her into their lives. She went to dances, birthday parties, a wedding, a powwow, neighborhood barbecues and festivals. She was invited home to dinner, to meet friends and relatives and onto boats of all sizes, from a canoe to a towboat.

She wrote the book and took many pictures along the journey.

At the invitation of the Ste. Genevieve Tourism program, Ms. Harper will be conducting two book signings — on Monday, March 9, and Tuesday, March 10.

The full title of the book is “Roadtrip with a Raindrop: 90 Days Along the Mississippi River,” published by Acclaim Press.

The author will be selling and signing copies of her book at the Ozark Regional Library in the Ste. Genevieve County Community Center from 5:30 to 7 p.m. on Monday, March 9 and at the restaurant Audubon’s of Ste. Genevieve from 4:30 to 5:30 p.m. on Tuesday, March 10.

“‘Roadtrip with a Raindrop’ is a celebration of America and of the simple moments that make life an adventure,” Harper said.  “In its 240 pages are 55 stories, with nearly 200 full-color photographs. Together, the words and images invite us to leave our agendas behind, to travel at the pace of a raindrop and to rediscover the fine art of letting life happen.”
