The Outlaws of Down Cthulhu
LA is primarily a horse and buggy town, small docks by the river; saloons; outlaws felt at home here.
California passed a law against Chinese entering. So they are smuggled in, ending up on railroads, the Chinatowns of LA and Lost Angels; also an underground railroad type of thing to move them to San Francisco.
Political reasoning was they were afraid they would take jobs from the citizens. Weird twist is it is against the law for them to enter CA, but once they are here they can’t be sent back. You must then prove absolutely they sneaked in, which is difficult. There are anti Chinese sentiments of course, even gang activity.
One of first families out here post quake live in a huge mansion, The Waitleys, from some place back east called Dunwich. Bunch of them came west post earthquake.
