Congrats. Eastern Indigos are the reason I wanted my first snake as a little tyke. I will have one one day. Post some pics!

Pat, you can't sell eastern indigo snakes across state lines. You'll have to find a breeder in Cali. Here is a list of breeders. It looks like there are 3 breeders you can contact.
