Book excerpt: How did Omaha get its nickname, “The Gateway to the West” and where can you gawk at the footsteps of the first human to walk in space? Just scratch the surface of a city best known for Warren Buffett, college baseball, and a great zoo and find far more than meets the eye. And Secret Omaha: A Guide to the Weird, Wonderful, and Obscure is just the book you’ll need to uncover all the stories of Nebraska’s lone metropolis. Omaha rises up out of the low broken bluffs along the west bank of the Missouri River and sprawls west across what was once the prairie grasslands of the Great Plains. The buffalo wallows have been replaced by a more urban mix of grit and gentrification, with tree-lined avenues, boulevards, and varied communities that hold on to their heritage for generations. There’s a giant fork in Little Italy and stories told in stone around what was the world’s largest livestock market. There’s an old blues song by Big Joe Williams about an Omaha intersection that’s now on the National Register, and Irish Nationalists erected a grand monument to the Fenian who invaded Canada twice. Anyone in Omaha can take a gander at Goose Hollow or visit a haven for herons, but now author and Omaha enthusiast Ryan Roenfeld takes you on your own behind-the-scenes tour of the Big O. With his book as your guide, you’ll discover a whole new side to the city that’s inspired him for years.
