I received a call from the county Director in charge of the county Commissioners. He apologized profusely and asked me to come back to the library. He said he would address my concerns with the library board again in January and apologized for the nastygram they sent me.
Still no resolution though... the policy has not changed although he insists that I am welcome to return with my double strollers and all. We'll see about that... I'm expecting another call from him after the library board meets so I can see what comes of this.
