In fact, as of Monday, global Tesla owners had their pick of 2,146 Superchargers at about 400 charging stations. And while an inordinate number of those were along the West and East Coasts of the US, there are many and more throughout the land.

Two years ago, Tesla started publicizing that it would take its Supercharger network nationwide, and a look at the present-day map it appears to have made good on that promise.
