Weigh-In Wednesday: Road Trip!

I've been racking my brain for something that I just could not live without during our pack out. Unfortunately, nothing stands out. But the road trip, now that's a different story. You see, I just made a 16 hour (2 day) road trip with two munchkins, my husband in a different vehicle. I had two things I could not have made the road trip without; Pepperidge Farm Mint Milano Cookies and an audio book.

Now, I could review the cookies but I don't have any on hand and I must be able to snack as I type and seeing as I'm visiting my parents, I can't run out to get some (they live in the middle of nowhere). So I will save them for another day.

And as we're getting ready to make another road trip I'm hoping some of you can help me. I'm in the market for a new audio book and am looking for suggestions.

What audio book can you not live without?
