Nebraska has begun to honor South Dakota enhanced concealed carry permits when in the possession of permit holders ages 21 and older. Earlier this month we reported on the reciprocity agreement with Delaware but since Nebraska is an adjacent state I'm confident SD residents will find this latest update far more valuable.
The official webpage on the Nebraska State Patrol website hasn't been updated with the changes as of this writing but we have seen news reports on various South Dakota publications that confirm this change.
