Remember when tarp surfing was a thing for a week or so? You’d head out to the garage and grab dad’s biggest tarp Then you’d tie a string to a corner, round up a few friends, and shoot that plastic tube, hips out and arms back, feeling like Gerry Lopez on a skateboard. Then you’d hit a rock and spend the next week picking gravel out of your palms. Well, we just stumbled across this ad from Mountain Dew and it makes us miss those gravel-plucking days.
