The storm that bought me a better tent.
I once pitched a cheaper tent near Grand Lake. Before I could even retrieve a bag from the car, a fast-moving storm swept in, collapsed the tent, and sent my dog running out just behind me. We both spent the night in the car.
Afterward, I paid attention to which tents had survived and studied those brands. The lesson was simple: in mountain weather, a well-built tent is worth paying more for.
