RollerCon

RollerCon is a five-day convention, held yearly in Las Vegas for members of the roller derby community.
The convention was first held in 2005 and is organized by skaters Ivanna S. Pankin and Trish the Dish.
The 2012 conference was five days long. There was skating. There was drinking. Not at the same time. Attendance was projected to be over 5,000 people.
There was one convention casualty: in 2020 when the COVID-19 pandemic caused officials to scrap it. That was deferred to 2021.
