As far as I know there is no state in the union that REQUIRES anyone to carry an ID. In most jurisdictions you need to only identify yourself (some not even that). That said, it takes some balls to excersize this right when confronted by a LEO and they typically can take you into custody until your identity is confirmed. You do need to carry a DL when driving.
