 Just this past weekend, six motorcyclists were riding through the park. One of them actually died. Another was hospitalized, and four others were treated for heat-related conditions. As we know, Death Valley is considered one of the most extreme environments in the world, and visitors are sharing how that heat feels. It's like a wave that hits you when you get out of the car. And this is where the heat finally really hits you. You realize just how hot it is. You start sweating.
