I do have a list of girls events on my website.
(And Tony apparently you didn't pay attention, my tournament is always USA sanctioned)

Annual tournaments with girls bracketing:
Ark City -- December
Derby -- January
Atchison -- January
Rose Hill -- January

Annual girls tournaments:
Girls Midwest Regional Wrestling Championships - late Feb- early March

USGWA also has a Kansas State Championships over High School State weekend.

Though for 2005-2006 Desoto and Topeka Terminators have expressed interest in girls bracketing.
If you know of any others please let me know, and I will get the word out.
Thanks
