The Salt Palace Museum, Grand Saline, Texas

I had no idea that the salt we use from the Morton salt container comes from a small town called Grand Saline in Texas. The city of Grand Saline is home to one of the largest, purest salt domes in the United States with a supply estimated to last 20,000 years. The museum's outside walls are made of pure rock salt.

During World War II thousands of British pilots learned to fly at six civilian training schools in the United States. The first of these schools was in Terrell, Texas. After the United States entered the war, American Aviation Cadets also trained at the school. Approximately 2,200 Royal Air Force and American Army Air Force cadets trained at Terrell and around 1,470 graduated between 1941 and 1945.

Mammoth Cave National Park, Cave City, Kentucky

This is our second trip to Mammoth Cave National Park, so we did not take any of the tours. On our last trip in 2011 we took the Historic Tour, but I have no pictures from that tour. The pictures here are just from the Visitor Center, which has a wonderful display and explanation of the cave system. Mammoth Cave is the most extensive cave system on Earth. It took about 4,000 years of water intrusion for the cave to form, carved out of sandstone and shale. Over 365 miles have been surveyed and Geologists think there could be 600 miles of undiscovered passageways. It is over twice as long as any known cave.
