The first Gathering of the Juggalos was held July 21st and 22nd, 2000, in Novi, MI. It was a two day convention/festival for Juggalos. There were free tattoos, autograph booths, an Eminem dunk tank, lots of rare merchandise, a haunted house, an ICP stage set museum, a haunted house, two JCW shows, and two night-time concerts.

The first night's concert starred Perpetual Hype Engine (filling in for Myzery, who was a no-show), the Kottonmouth Kings, and the Psychopathic Rydas. The second night's show consisted of Blaze Ya Dead Homie, Project Born, Twiztid (who played an excellent set as the sun fell), and the Insane Clown Posse.

After the second show was supposed to be a Faygo Armageddon, but it was canceled by the police. Angry Juggalos knocked down fences and set various buildings on fire.
This year's Gathering of the Juggalos is being held July 13th-15th in Toledo, OH. ICP and Twiztid are confirmed appearances, and the Kottonmouth Kings and Vanilla Ice are rumored to be on the bill as well. Tickets go on sale Friday, March 9th, 2001 for $90.
