"America" is a vast area. Too large to be considered a cultural region.

For me, in particular, I grew up in New Jersey. My primary culture was South Jerseyan, heavily influenced by Philly. Then New Jerseyan, more influenced by NYC. Then Northeast and Mid-Atlantic. Then American.

The culture did not suit me, though, and I have spent many years in the Pacific Northwest now. So now, I identify primarily as someone from the Pacific Northwest, having spent time in both Washington and Oregon--Mostly Seattle, but also kind of the boonies for a little while. I am a Pacific Northwesterner first, a New Jerseyan second, and an American third.
