Vette 6387, I can’t tell whether you live in CA as you have not identified a state of residence. I do live in CA, and I can tell you that dairy farmers are being pushed out of this state by both population expansion, state regulation and state taxes.
The San Gabriel Valley used to be full of dairy farms. I worked in an electronics company located on Arden Drive in El Monte which was formerly the Arden Dairy ranch. Those dairies then moved out to Chino. Once Interstate 15 was built, tract homes were built surrounding the dairy ranches. So, the dairy farms moved farther out to areas in the Hemet Valley where once again tract homes are being built next to the ranches.
As with the agricultural farming in the Central Valley which is being driven out by absurd State of California water regulations, so too will the CA dairy ranches eventually migrate out of state. Just one more industry killed by CA politicians.
When the San Gabriel River Freeway (Rte. 605) opened in 1966, it ran through dozens of square miles of dairy farms in the lower San Gabriel Valley. Cerritos used to be known as Dairy Valley, and La Palma was Dairyland until the late 1960's. By the early '70's, all the dairy farms were gone.
Because the dairies attracted so many flies, newly-established housing tracts in dairy country were soon followed by lawsuits by the new homeowners against the farmers. In the 1960's and 1970's, a lawyer who effectively represented the farmers in such cases gained a reputation as the "fly attorney," but he was ultimately unable to save the dairies.
