McDonalds (various): Not a very inspired choice, but there are times when there is nothing more satisfying than an Egg McMuffin, a hash brown and a paper cup of orange drink eaten straight off your lap in your car. To eat this breakfast at an actual McDonalds franchise would be depressing, but to eat it as sustenance for a road trip is sublime. Make sure to get extra napkins in case you spill any ketchup, and try to stop as soon as possible to throw out the greasy wrappers - the smell lingers in a bad way. If you're down south you can even get your eggs on a buttery biscuit, which is decadent, but messier. Perhaps the only meal at McDonalds where you believe that the food you're eating is actually real.
