PokerWiki is – you guessed it – a wiki for all things poker. It’s actually an impressive resource. For instance, it has a map of casinos in the Bay Area. Also, it appears that local casinos don’t spread No Limit Hold ‘Em because it’s illegal in Santa Clara County (according to the Bay 101 entry), and maybe in the state (according to the Lucky Chances entry).
I’ll have to dig into this site more deeply.
