No fear, in Cali or Texas your SD niche will be covered - enough demand for pure locals is there that people are already collaborating to ensure that we have the local specific pairs that can reproduce in Texas. California has a slough of breeders who aren't going anywhere since the demand is consistent enough. It's places like Ohio, Michigan, Mississippi, Alabama, Georgia, West Virginia, and many many many more states that will suffer from this.
Don't be knocked down. This fight is not over.
