I'm board member of the Reptile and amphibin society of Philadelphia (R.A.S.P.), we just started about 5 months ago. I can tell you it's not the easiest thing to do. You'll need some people really willing to dedicate some time to it.
If you have any specific questions about getting started I may be able to answer some of them just E-mail me at Pcurtus@aol.com
As for us we're having a great meeting this month. On nov.18 the monday following the N.A.R.B.C. show in philly R.A.S.P. will be featuring a presentation by world renowned herpetoculturist Bill Love. There will be a cover of $5 for non-members but membership is only $10. For more info E-mail me or swing by our table at the N.A.R.B.C. show.
