We were pushing hard to make Natural Bridge before nightfall, and would have made it. At the wide, flat bottom of the valley, with this mighty precipice I stand at the top of now ahead of us, I knew we had time. Even pulling 35′ of trailer with an engine prone to overheating at altitude, there was plenty of time to make the mileage. I just needed to be steady with the climb. A few short stops along the way, letting the engine idle back to cool.
