Rivian Waypoint EV Chargers Now Operational On Lake Michigan Shore
This is a collaborative effort by Rivian, the state of Michigan and nonprofit Adopt a Charger to set up a Lake Michigan EV Circuit.

Apparently some 15 such Rivian Waypoints are already up and running and the network was officially launched with Gov. Gretchen Whitmer attending the event held at Holland State Park, at one of the locations where a new charging station was added. She is quoted as saying
The plan is to have 30 Rivian Waypoints operational along the coast in order to create a Lake Michigan EV Circuit that will help fill important gaps in the EV charging network that’s already in place in the area. Another goal is to allow visitors to drive their electric vehicles from one state park to another and have the possibility to charge in a more remote place.
