All over the USA homegames are played. The basis of poker is just a couple of players coming together and have fun over a few quid changing hands. Find some friends that share the passion and get together once a week for a game!
The casinos just provide security for competitions and bigger cashgames.
Oh I absolutely agree with you, I play almost twice or tree times a week in a homegame with my friends at uni! I was just more talking about on a nationwide level if you know what I mean?
