Thanks to Tesla, dense Supercharger network made us possible to travel long distance and almost everywhere in US. I'm currently living in Seattle area. While ownership of X 75D, I noticed visiting nearby National Parks(Olympic, North Cascade, Rainier) are somewhat concerning for me due to Supercharger coverage. This weekend, my friends will come to town and they want to make day trip to Mt. Rainier. But when I checked distance and Supercharger location, it raised my concern. Seattle to Sunrise is almost 200mile round trip including hill climbing and non of routes has Supercharger station. Issaquah, Tacoma, and Enumclaw stations is not yet built. EPA range for X 75D is 230mile but not sure it's safe to do day trip. Has anyone done this? What was your experience?
