How you know it's a fast food nation
CNN has a gallery of some products available at a recent auto convention, including a fry holder that sits in your cup holder. Keep looking in the gallery, and you'll see a grill you can attach to your trailer hitch.
However, it turns out a better product is already on the market -- a fry holder with a ketchup cup attachment!

Seriously, folks. We need to get better at separating driving from other activities.
