In California, we break it down into counties because the counties are so big (bigger than some Eastern states), and there are so many people here.
Thank you for your comment. In Maryland, we also operate the Master Gardener Program at the county/city level. We’re in 20 Maryland counties and Baltimore City. https://extension.umd.edu/mastergardener/about-maryland-master-gardener-program
