I’ve only ziplined once when I was younger but I’m pretty sure that it’s not a great thing when you crash into the side of a mountain while doing it. Call it a hunch.
And this is exactly why I don’t trust Wile E. Coyote. His teachings made me believe that crashing into a mountain would be quickly brushed off after you turn into an accordion and/or leave a body-sized hole in the wall. But nope. You just scream and get injured. When will the lies end?
