In the spring of 1945, while the Manhattan Project was still in development, other highly secret — more tangible — initiatives continued apace as the tensions in the Pacific theater grew:
“Milepost” was the mammoth westward surge of US supplies to prepare Soviet Forces in the Far East for their coming war with Japan. Simultaneously, under “Project Hula”, Russian sailors by the tens of thousands passed in the opposite direction to Cold Bay, Alaska, where they were secretly trained to operate “made in the USA” warships when the Soviets declared war on Japan. Meanwhile, ongoing planning, codenamed “Keelblocks,” for the direct US support of Soviet combat operations against Japan was further refined by staffs in Washington.
Author D. M. Giangreco sheds light on Projects Milepost and Hula, as well as the Keelblocks planning, and discusses how it came to be that these secret US initiatives have remained off the radar screens of both historians and World War II history wonks.

The Ozarks Spook Light: History, legend, and speculation
Thursday, October 30, 2025 @ 7 p.m.
 |
In this book, Larry Wood details the history of the Ozarks or Tri-State Spook Light. Reaching its peak as a tourist attraction during the mid to late twentieth century, the nightly phenomenon has been drawing the curious to an out-of-the-way spot near the Missouri-Oklahoma border for almost a century. The book also recounts the supernatural legends that purport to explain the strange light, and it chronicles the many scientific and pseudo-scientific investigations into the light's origin. One chapter, called "Close Encounters of the Spooky Kind," relates experiences involving the light that various people have reported over the years, from the unbelievable to the mundane. A separate chapter covers the author's own extensive experience with the light, and the book ends with a discussion of what causes the mysterious light.

The world's most iconic radio show, The Grand Ole Opry, celebrates its one-hundredth anniversary this year. But few people are aware that the inspiration for the Opry took place not in Tennessee but in the Ozarks. In honor of the Grand Ole Opry's centennial, historian Brooks Blevins takes us back to a small town on the Missouri-Arkansas border more than one hundred years ago to explore the story of the Ozark Origins of the Grand Ole Opry.
Presented by Brooks Blevins
