Hi RedHot! Welcome to the Beta board!
I'm not a member of a Texas chapter, but I do know that Texas is one of the states that Beta really thrives in. I believe there they have triple chapter names (Alpha Alpha Alpha chapter, for example)! Chapters come in all ages and sizes, mine is 13 sisters strong and we range in age from 25-39. I have heard of some Texas chapters having 30+ members (that's pretty big for BSP!!).
If you want to find out more about Beta, you can visit our website:
www.betasigmaphi.org. The site explains about how to get started looking for a chapter and, of course, you can always come here with questions!
Also, you can check out Erica's Yahoo group called "The Rosies". It's a group for PNMs looking for info about Beta. The info is a few posts down on this board.
