This was just posted in the fb Iowa Tesla Users Group: “According to the Tesla Supercharger “Find Us” website. They will be adding a Supercharging station (# of stalls and supercharging version unknown) later this year in Waterloo!”
Yes, there are lots of sites on the “find us” map which indicates Tesla’s approximate intentions for coverage. Many new sites have been added in the last day or two. However, we don’t add them to supercharge.info until there is a definite location identified. Often the sites on the “find us” map are marked as “coming soon” for years before anything happens.
Thanks, did not know that!
