Just as an empty stomach will make the most mediocre food taste excellent, sleep deprivation can make black-tar gas station coffee taste like the nectar of the gods. Anyways, interstates and backroads are not the place for an expertly pulled espresso or a custom blend from Nicaragua (no offense, Nicaragua!). Hot, maybe burnt, and cut with creamer and white sugar, road trip coffee exists to move you along, like a good song on the radio or a sky at dawn that's pretty to look at. You can always count on a gas station to have it. You can always count on it to keep your eyes open.
