That great WI company Kwik Trip has started adding high speed chargers to their stations recently, so hopefully they will become a lot more commonplace in the near future.

There are quite a few apps in addition to the ones that the EV manufacturers provide for their owners, that map out chargers along pretty much any route of travel you may want to take. Granted, there are some areas that have far fewer than others, but with some relatively easy planning you're very unlikely to be left stranded anywhere.
