Do they happen to cash checks here? Or does anyone know where i can cash a check in California City or near by? Thanks.

Cactus market in California City cashes checks that's where I go

No unfortunately they do not. Depending on where it came from the gas station by the bridge heading towards Lancaster is the only place in Mojave that does as far as I know. Cactus Market may be able to help you in Cal City they open at 7!
