TanaCon (2018)

TanaCon (2018) stands out for catastrophic overselling: 5,000 tickets sold for a venue holding just 1,000, forcing fans into Anaheim parking lots where 8 heatstroke cases were reported in one day. This is 400% more oversold than the average convention disaster and 50% more dangerous than #7 Burning Man Mud Stranding in immediate health risks, as the mud stranding caused 1 fatality versus TanaCon's 12 hospitalizations.
