Talk about low-hanging fruit, yet I'm not aware of any Supercharger in any national park nationwide. Why? DOI Secretary Sally Jewell would be all over this. With the air quality problems in many national parks, like Yosemite, Grand Canyon, Great Smoky Mountains, Zion, Yellowstone and others, seems like NPS would really want to promote EV driving to parks. There's plenty of parking lot space for supercharger installation, what gives?
