The Flaming Chickens FRC 1540 hold a Bunny Bots game every year. Some details can be found here.

http://www.team1540.org/girlsgeneration I am certain that if you contact them they would gladly give you more information.
After attending their GG event in 2011 our team, FRC 2046, decided that we needed a GG event in our state. We teamed up with FRC 1540 to bring an official FRC field to the NW for both of our GG events and to use the event as training for volunteers in preperation for the likely move to the district model in the NW for the 2014 season.
