In Miami many, many moons ago we had a really great "Ladies' Luncheon". We got our food and drink, sat down like adult women, went around the room introducing ourselves, telling a bit ourselves, and then had a talks about what was going on in biz, where we thought it was headed, etc. I met most of the women I still know in this biz that day and it would be wonderful it could be duplicated.
However, an ongoing dues required "club" just doesn't seem needed in any way, shape or form, IMHO.
