Locale for many cabs

NAPA

The cabernet sauvignon (often just “cab”) grape has been around since the 17th century, and is the result of a chance crossing in southwestern France of the cabernet franc and sauvignon blanc grapes.

If you’re referring to the term “cabs” as taxis, and “Napa” as Napa Valley, then the locale for many cabs in Napa Valley, California, would likely be the city of Napa and the surrounding areas in Napa County. Taxis are commonly found in urban and tourist areas, providing transportation services for residents and visitors exploring the vineyards and wineries in the Napa Valley region.
