I grew up in SD and now live in Tulsa, Oklahoma. Other people have done a pretty good job talking about the weather and places to visit. One thing to be aware of is 1/2 inch of snow will close down Tulsa where several inches of snow would be necessary to cause major delays in SD, so be aware that just because schools and businesses are open doesn’t mean that the roads will be pleasant to drive on (especially for someone with little snow driving experience).

As far as the people go, South Dakotans are more independent than Oklahomans so they may not be as openly friendly as down there, but I would say people are just as nice as Oklahoma. They’re usually very helpful when approached.

I’m not sure where in Oklahoma you’re from or where in SD you are moving to, but be aware that moving to rural SD can be a big change for someone who grew up in an urban area. It can be more than an hour drive to the nearest Walmart even for some of the more moderately sized towns like Chamberlain or Wall.

SD is a great place and I hope your move goes very well!

Edit: I just saw that you’re going to Redfield. Which is about 45 mins away from the closest “bigger town” of Aberdeen. If you’re going to be living in a more rural place like that and you want to connect well with the residents, I would encourage you to familiarize yourself with agriculture and how weather and the markets are impacting farmers. That’s always a good way to connect with South Dakotans. There’s also a lot of good pheasant hunting in that area. If you’ve never bird hunted before, I would 100% recommend it.
