Tilted Thunder Rail Birds is a Seattle based, all-female, banked track roller derby league. We are a 501(c)3 nonprofit organization run by a volunteer force of skaters and league members committed to promoting and raising awareness of women's roller derby, especially banked track roller derby. TTRB is comprised of strong, friendly, intelligent, enthusiastic women from all walks of life pursuing emotional growth and physical strength by challenging their perceived limits. As a league, we also wish to promote mental and physical empowerment, development of skills, loyalty on and off the track, individuality, and friendship - throughout the entire sport, both locally and nationally.
