Our home teams play each other, except in some exhibition games like the Rat City ones, or Friday night fundraiser scrimmages.
Atomic City did play the Lava City Cinder Kittens ("B" travel team) during Derby Daze last year, before the infamous AoA/Bakersfield game.
Atomic City is not a WFTDA member league, so they can play whoever they feel like playing. They would play teams closest to them for the sake of travel expense and convenience. They'd also want to play teams within a similar skill range if possible.
Rose City is a very competitive program, so our home teams are often stronger (or much stronger) than visiting teams from around the region.
That clear it up?
Also, WOJ plays other WFTDA ranked teams (http://wftda.com/leagues
) and AoA plays other takers who want a challenge.
