Writing in the Car

I have been searching all over for a writing notebook I had taken from my daughter's stash a few months ago (she is so over glittery cupcake designs) and I finally found it!

This notebook will be for the car. I will keep it with me at all times so I can write down any ideas that come to me as I look out the window or listen to the radio. Don't worry, I won't do it while I'm driving. My husband usually drives us when we're together, so I can sit and write my heart out.

Do you keep a notebook in your car?
