Here’s the photo highlights.

  1. I bet that was really interesting! I use to work in a police department and saw all kinds of amazing things. What makes us so curious? 🙂 Thanks for sharing. Bet it helps you visualize when you write.

  2. It’s important for me to have a visual image, even if I don’t use it exactly the way it is. Even knowing the spacial layout helps.
