If you want to grow up to be an adventurer, it helps to have an adventurous childhood. Author Rinker Buck grew up in New Jersey, one of 11 children living "a normal middle-class life" — or it would have been normal, if not for their father, a one-legged barnstormer and magazine publisher.
"My father was very adventuresome and engaged his kids in things like learning to fly and horseback riding," Buck said. "Other kids were playing golf."
In 1966, when Buck was 15, he and his 17-year-old brother, Kern, bought an old Piper Cub plane, rebuilt it in their barn, and then flew it from New Jersey to California. Buck did most of the navigating, following roads and railway lines using maps and eyesight; they had no equipment, no radio.
"What I learned from that experience was that, first of all, you could escape the bonds of ordinary middle-class existence by doing something like that," Buck said. "And, number two, that you could push yourself to achieve things that other people wouldn't think of."
That adventure became a memoir, "Flight of Passage," a national bestseller.
Since then he's driven a covered wagon the length of the Oregon Trail; and, in 2016, at age 66, built a wooden flatboat (named "Patience") and sailed it down the Ohio and Mississippi rivers to New Orleans. His new book, "Life on the Mississippi," is about that trip. Buck will be in the Twin Cities for events Aug. 12-13.
We spoke with Buck about his book's "disguised agenda," the hidden history of our greatest river and how to slow reality down. This interview has been edited and condensed.

Q: Before your flatboat journey, people told you the trip was too dangerous, warning of whirlpools, beachings and capsizing. Why did you go?
