Nature's beauty and cultural significance unite at the Wichita Mountains Wildlife Refuge. Join me as I explore how the majestic bison returned from near extinction, and you'll see why this refuge is one of America's amazing places.

Thank you all for commenting with your times for last week's Old Man's Cave puzzle. The average time was around 9:51, with a blazing best time of 5:46. For me, last week's puzzle was a tough one I came in at nearly 21 minutes!) It's wonderful to know we have such a range of times and to know that we're all having fun together. Please keep sharing your times and experiences; I love the camaraderie and excitement.
