Santa Cruz -v- Sonoma.
S Cruz and environs promote similar numbers of tourists to that of Sonoma (forget Marin), each with their own attractions. S Cruz, beach and sidewalk both famous for years with the trains from both railways. Not much museum room though!

Sonoma has vineyards, cute touristy towns like Healdsburg and Sonoma. Napa is not far away with its Wine Train and more vineyards. Tracks still run through from S Marin to Willits for excursions - if someone is willing to spend the money! Plenty of room for a museum which would increase tourist traffic.

Sonoma wins although it looks as though GGRM has its heart set on S Cruz.
