“Of. Fucking. Course!” The demons inside my head are screaming at me as I skid down sun-drenched gravel and onto the highway shoulder, narrowly avoiding a rock kicked up by an old Ford Ranger. I am rage-walking in the unrelenting sun of Death Valley National Park, whipping my head around my shoulder to double-check that Ben is still behind me, and praying that at any moment, my heels will sprout wings. It’s nearly 2pm, we’re out of water, and our car is definitely not where we left it. In the distance, thunderheads shroud neighboring peaks, filling me with envy for the comforts of water and shade. My skin is seething as my stomach churns trail mix into knots. I steady my breathing, look both ways down the dusty, two-lane motorway, and shove my thumb into the air, indignant.
