I found out about this "Round-Robin" photo challenge over at Babyshark's. I'm not sure what "Round Robin" means, but I know Carly of Ellipsis fame is involved as well as several others whose journals I enjoy. But, it gave me the idea to share these two pictures that I took a while back.
They may seem pretty typical but each picture has a story behind it. Try to guess what the mystery is. I'll give you a couple of hints and come back either tonight or tomorrow to reveal the mysteries.
Hint #1: If you look at the picture of Door #1, it actually reveals the answer to it. But, you'll have to look closely.
Hint #2: As different as these doors are, they are related in some way.
