If you were not so far away,I would be glad to work with you.
You could start by putting flyers in pet stores,pick a public place to hold your first get together,make sure you let people know it is for Bettas.
See how many have an interest and how many are breeders.
Even non breeders are great to have,you might turn them into breeders.
I am pretty sure the IBC had a convention in Lancaster a few years back.
Good luck on it,I would join if you got one going,could not attend meetings,but would give you all the support I could.
The IBC is a good place to start,they will give you an assist in getting one started.
I would not mind the drive to Lancaster for a show.
Now you got me thinking about it again!
