Slope-Surfing is a real thing, don't @ me. It's a thrill-seeking adventure sport that involves hurtling down steep, sandy slopes at high speeds, often with nothing but a board and a prayer.
You might be wondering, "Why would I, a sane person, voluntarily strap a board to my feet and careen down a dune at 50mph?" Well, it's because you're not a sane person, and also because it's a blast. Like, have you ever felt the rush of adrenaline as you crest a 30-degree incline and realize you still have 10 seconds to live? It's like that.
