I’ve visited the Jewish communities of middle America. Plainly- They are not much different than the smaller town communities in the tri state… The difference is they may come off as more American in their demeanor despite being extremely devout/religious Orthodox Jews… The reasons could include the fact that they are 5th,6th generation or have lost count. They live surrounded by Christian Americans, far from the Jewish metropolises of the east and west coasts. Also, the moral fiber of their gentile neighbors is of a much higher standard as well, so there is seemingly no harm in adopting the American mannerisms to a certain degree.
Hats off to these communities who are serving HKBH in these remote areas- it’s much harder for them without the landau or the 17 kosher restaurants on one block. Some of them only have a small butcher/grocery store and that’s IT. One city i go to has NOTHING. Literally nothing. They make do with shipping food from the nearest community.
So to answer the question- I’m sure shabbos is very holy in these towns and probably freezing cold for about 75 percent of the year.
