There are several cultures in the US. Most of them are regional. I grew up in rural, central CA and hav stayed mostly to the west of the Mississippi. Gun culture, going out target shooting with a group of friends. Rodeo/cowboy culture, wearing western boots and hats even if you end up working an office job. Hotrods, fixing up old cars in to street racers. Low riders. Surfers/skateboarders. Lumberjacks in the Pacific Northwest. Cajun/swamp people. A culture doesn't have to encompass the entire nation.
