Slack Grove was held in June 2021. It was scheduled for June 11 - 13, 2021 but the date was moved to 18 - 20 June 2021. It was the fifth event of The Grove Gathering (although the fourth did not happen due to the pandemic). Participants at risk were required to be vaccinated for COVID-19.
Thursday[]
Thursday was set-up day, although the paths had already been mowed and cleared. The main pavilion was set up, and everybody there slept under it. Dolphin Lagoon aka Mermaid Pond was ready for swimming; it had been a mud pit, but then the rains came and filled it.
Friday[]
The event wasn't just for SubGenii. Discordians and Pastafarians; others also came. Most people were Pagans/Wiccans, but not all. Some visitors traveled there from out of state, but most were local. Admission was by donation, but those in groups who were recommended to get COVID-19 vaccines by the Center for Disease Control had to present proof of vaccination at a troll booth. Maybe due to the restrictions, there were fewer people than before, with two times 23 plus 3.
There was an opening ceremony, and then singing, instrument playing, and dancing. The Cloved Lemon Kissing Game was played every day and night. Bottled water and other essentials were sold at cost. The fireflies were free.
Saturday[]
A free-the-slaves event was held in honor of Juneteenth. Most of the "slaves" were children, who were taught by a teacher and others about what slavery was and why freedom was so important. People also saw a slavery drama. Some talked about forming a local medieval recreation chapter. Attendees enjoyed a dance workshop, a spiritual workshop, and a performance by a comical magician. A musical group sang and performed.
Sunday[]
Father's Day and the Summer Solstice were the themes of Sunday. People made tributes to their fathers, There was a ceremony to welcome the Summer Solstice.
There was also an awards ceremony which was mainly tongue-in-cheek. The Best Father award went to the unknown father of Bunny the gray kitten. The best body painting award went to painter Gypsie Skripto and "the body" Urso Negro who had gotten married to Gatina at X-Day Underground in 2018. The Disco-Rdian Dancing Trip won for Weirdest dancing which they claimed they had also earned the previous year (when the event wasn't held). Best Gatherington Gazette reporting went to Miley Spears, and Best Name for next year's event was Rainbow Grove made by Dolphin Blue.
The main structures at the event were the pavilion and four portapotties.
