Lost worn cookbook titled 'The Joy of Cooking' with handwritten notes, possibly left at a friend's house or near a car in Rapid City.

I lost my favorite cookbook, 'The Joy of Cooking', while visiting a friend's house in Rapid City, South Dakota. It's a bit worn out and has some of my own handwritten notes and recipes tucked inside. I'm really worried I left it there or maybe it fell out of my bag when I was walking to my car.
