While driving around the country on a mega-road trip last year, I relied on a lot of things to keep me going: gas, protein bars, peanut butter pretzels, water, and coffee. Lots and lots of coffee. I was on the road for four months drinking two cups of coffee per day, running through disposable cups from the of whatever Holiday Inn I stayed at the night before, from places like McDonalds, Circle K, Love’s, Pilot Flying J, Panera, Starbucks, and Dunkin (née Donuts), and from gas stations where both the coffee and the cups had been sitting on the counter for an indeterminate amount of time.
