If suddenly Americans stopped traveling by car, not only would the atmosphere be cleaner and our need for wars curbed -- but Slim Jims and Combos would cease to be a viable market product.
Seriously, Slim Jims have to be the most disgusting food item ever created, yet they seem to be the bees knees for traveling. I'd guess that a healthy percentage of highway accidents involve taking off that wrapper to get to the flavored "processed intestine" goo. [I'm guessing this will not result in complimentary product -- and I'm okay with that]
And Combos, which seem to be completely unthought of in my life, unless I'm somewhere in the midst of the interstate highway system. I'm pretty sure I am not alone in this thought.
