Seattle's women's flat track roller derby league, Rat City Roller Derby, got its start in April 2004 as Rat City Rollergirls and quickly built a large local following. Rat City is a founding member of the Women's Flat Track Derby Association (WFTDA), and has achieved success on the WFTDA stage, qualifying for WFTDA Playoffs every season, including a second-place finish in the 2007 WFTDA Championships.

This poster advertises the 2005 Inaugural bout on March 26, at the Southgate Roller Rink in White Center, Washington. Tickets sold out within 24 hours and a crowd of approximately 600 people saw Derby Liberation Front and Throttle Rockets win the initial bout over Grave Danger and Sockit Wenches. After only two more bouts in White Center, the league had to move to a larger space in Magnuson Park to accommodate the overflowing crowds.
