My trailer broke down at 5pm on I90 on a Memorial Day weekend 50 miles west of Sioux Falls, SD. Limped off I90 and happen to be a trailer dealer. The dealer was closed, but they left on the window the four names and numbers of the men that worked at the dealership. I called one of the numbers, the man said he was 50 miles away, but told me to go 1/2 mile into town, see Bill, and he could take care of it.
I went into town, now 6pm on the Friday of memorial day weekend. Bill stopped what he was doing and fixed my issue.
As someone who travels and lives cross country for the past 30 years, I can tell you what goes on in South Dakota does not go on in the majority of the USA. You live in a magical place that still has the values of the pioneers and the greatest generation - today. Regrettably, most of the USA doesn't share the values of the people of South Dakota.
We have targeted South Dakota as one of the states to retire to (although unlikely). If we had young children, I would sacrifice most anything to raise kids in South Dakota.
