Imagine skiing without sight. The world is black and you move only when a disembodied voice tells you to do something. I wanted to do more than imagine this—I wanted to feel what it was like to ski blind. So blind ski guide and Teton Adaptive Sports founder Kurt Henry stuffed my goggles full of goggle bags, and then we went for a few runs at Wyoming’s Grand Targhee Resort.

Here’s what I found: Skiing blind is a mixture of total terror and total trust, and it’s one of the weirdest sensations I’ve ever experienced.
