Melody, 2 things.
1. Find out how many are in your local area.
2. make some calls and contact your Hdq to see if any interest has been shown.
Once this has been done, then see who is interested in being an Officer etc.
I would guess intiately, that if you do this, you will have to be the ram rod so to speak and get it rolling.
A lot depends on how active the group feel they want to be and do.
I would say starting off, just make it a social gathering and extend from there. Maybe once a month for social purposes, maybe cocktails at the same place monthly. The numbers will ebb and flow depending on time restaints of the ladies.
Dont be frivilous but on the other hand dont be to regimented. It is to be a fun time to gather and BS as it were. Have fun and relax or what ever!
Good Luck!
