Nevada Explanation
We had no idea we were camped next to Area 51 along the Extraterrestrial Highway. It was a beautiful but lonely area. After discovering where we were, I wanted to write a spooky story. I remembered when we were traveling on our honeymoon, he got tangled in his sleeping bag. It was perfect for my story.
We never did figure out how he got turned around in the sleeping bag. Although, he has been known to sleep walk. Maybe he was abducted by aliens and returned upside down in his sleeping bag.
