Rocky Mountain Potato Salad

I'd guess in the early 2000s, I started buying "Rocky Mountain Potato Salad" several times at a supermarket, but I haven't seen it for quite some time, and I'm NOT claiming this is the same exact recipe, but it is, at least, similar. The supermarket sold the salad from the deli case, and if I remember right, the store didn't make the potato salad themselves, but rather they bought it ready made. I checked, and there are a number of recipes that are called "Rocky Mountain Potato Salad," but why exactly the name "Rocky Mountain Potato Salad" is used, I do not know (ahh, maybe because it's easier than saying Appalachian Mountain Potato Salad or Adirondack Mountain Potato Salad? hahaha).  

Ingredients:

2 pounds small red potatoes, cooked (but not mushy), then halved or quartered, depending upon size
1/2 cup chopped walnuts
2/3 cup chopped red onion
1 rib celery, chopped
1/4 pound bacon, chopped
1/2 cup sour cream (reduced fat type is fine)
1/3 cup smoky barbecue sauce  
3 tablespoons chopped dill
1/2 teaspoon ground black pepper
1 teaspoon salt

Cook the potatoes in lightly salted water until they are cooked through, but not mushy. Meanwhile, cut the bacon into small pieces, saute it to the desired level of crispness, then drain it on paper towels. Cut the small potatoes into halves and the somewhat larger potatoes into quarters. Put the potato pieces into a bowl, add the red onion, the bacon, the chopped walnuts, the celery, the chopped dill, the pepper and the salt, add the sour cream and mix to lightly coat the salad, then drizzle the barbecue sauce over the potato salad. Gently give the salad just a couple of folds to distribute the barbecue sauce a little into ribbons running through the salad (it doesn't have to coat all of the pieces of the salad).  

 WORD HISTORY:
Country-This word is related to the compound forming elements "contra" (as in "contraband") and "counter" (as in "counterattack"), both indicating "against, to be opposite or in opposition," and both are Latin-derived forms borrowed by English ("contra" from Latin, "counter" from Latin-based French). "Country" goes back to Indo European "kom," which had the notion "by, with, near, beside." This gave Latin "com" and its variant form "con," meaning "together, with," which was given the comparative suffix "tra," a form of "ter," which produced "contra." This was used in the Latin term "terra contrata," meaning, "land opposite one;" that is, "land spread out in front of one," often rendered as only "contrata," which passed into Latin-based Old French as "contree," initially meaning, "countryside, the region immediately around cities or towns." English borrowed the word as "cuntree" in the mid 1200s, but its meaning more and more meant "one's homeland" and "homeland to a particular group of people." The word also took over much of the later expanded form "countryside," as a short form of that word: "Karen doesn't live in the city, she lives out in the "country(side"), or, "We're taking a few days vacation to get out of the city and go out in the country(side)." But that idea of "countryside, rural lands," had been present for quite some time, as "the region immediately around cities or towns," but centuries ago, because cites/towns commonly had walls around them, it made the contrast much starker.
