The CVG video explains how to glitch into North Yankton in GTA Online. It's a bit convoluted, but here's a summary: First, you need to replay the prologue mission. Once you reach a specific point on the map, a friend needs to invite you into a closed session of GTA Online. Once you've joined that session, you need to use a helicopter to head to the bottom right area of the map where you should see some snowy mountains floating in the air - obviously something that isn't supposed to happen. Continue flying toward the mountains, and you'll find yourself over North Yankton. While in North Yankton, you can get others into the area by repeating the steps. You can find all of the locations from the two missions of GTA V taking place in North Yankton.
The area's presence in GTA Online suggests North Yankton may officially be added in an update one day. It's also possible Rockstar will fix the glitch before then, so check it out while you can.
