All events are put on by local organizers. As this date was just announced in the last few days and organizers are still putting on May Day events today, they will be prioritizing June starting next week. We are in communication with organizers in Charleston, and I'm sure they could use some help. I believe you're in our organizer Discord, right? Please let us know if you'd like to support them in organizing an event in Charleston and we can put you in touch directly next week!
