From Gun Rights Watch:

As of July 1st this year, a new law allowing both South Dakota residents and visitors to carry concealed handguns called Constitutional Carry will go into effect. Gov. Kristi Noem tweeted yesterday that she will sign the bill today, which had passed the House and Senate within the past few weeks.

South Dakota is the 13th state to pass such a law. The state has restored the rights of its citizens to protect themselves however they see fit without government interference.
