The Dai Loi Museum in Locke (about 30 miles south of Sacramento on the river)
is a circa 1920s-30s Chinese gaming hall that was abandoned with all tables
and related goods intact and has been preserved.  It is usually open on
Saturdays and sometimes during the week.  Not sure if they have a web page but they
do have docents who man the phones.  It has the gaming pieces all set up,
tables, and many other artifacts related to Chinese gaming.  It is worth a
visit/study.

We find the go pieces (normally white but a few black) at most sites, both
the "chinatowns" and mining sites occupied by Chinese.  I also have come across
an occasional domino.  These are usually interpreted as related to
gambling/gaming.

The reports on the Riverside Chinatown site has a chapter on gaming also.
