The 2022 event is the eighth rally and still the only one of its kind in the United States. Tesla owners are invited to come explore the beautiful drives the southern Black Hills has to offer. The cars will be on display for viewing and questions on Friday evening. For 2022, the event is being capped at 200 participants.
