n'est pas

Whilst on my morningly drive, coasting at a good 70mph northbound on 85, I noticed that a highway patrolcop had pulled over some poor speeding soul, or had otherwise decided to pull to the side of the road and flash it's lights. Not that it's by any means an odd occurance, it's just what he had decided to pull over which made the situation quite situational.
Ever seen one of those mobile hot dog/sausage/other food item vendors hitched to the back of a truck?
No, he didn't pull over one of those. Not the truck part anyways.
It was just the vendor portion. Seemingly missing the truck needed to make this cart of tasty wares mobile. A guy was standing by the cart, looking perplexed. (or at least the three seconds I saw him he seemed perplexed.)
Which made me wonder what exactly was going on. Had the truck sped off leaving it's cart in the dust? Did someone hijack the truck and decide the hot dogs were just dead weight? Or was this cart somehow self-mobile...and going just too damn fast for the law...
It is one for the ages.

Hey, what the hell are you doing inside? Go make the most of the weather!
