The word for this week is unexpected.
Its adjective meaning: not expected; unforeseen.
I pass this piece of machinery on the way to a local restaurant and the sunlight hitting it in various times of day brought it to my attention unexpectedly. I loved the detail so decided to take a couple pictures. I cropped this one up close and personal so you can get the feel of the rusted textures and the complicated iron work associated with it. Can you guess what it is? I'll tell you more about it tomorrow. Until then, happy guessing!
