A city in California's Central Valley that is the home town of Brad Boimler, whose family runs a raisin vineyard there.
Modesto is a city in the farming country of central California. In Lower Decks it is where Ensign Brad Boimler comes from, a fact he is rarely allowed to forget by his shipmates on the USS Cerritos.
The Boimler family owns a vineyard that produces raisins rather than wine. It is seen in the third-season opener Grounded, set in 2381, when the Cerritos is impounded and its crew is sent home while Captain Freeman awaits trial. Boimler spends his enforced leave working the vines, oblivious to the attentions of the farmhands, until Mariner, Tendi and Rutherford arrive and draw him into a scheme to clear the captain's name.
The setting plays on the contrast with the Picard family's celebrated vineyard at La Barre, in keeping with the show's view of Starfleet from the bottom.
