Great Bend isn't terrible, but there are definantly parts of it that are deteriorating. Pratt just seems like a normal, small town.
I haven't been there for awhile, but Hugoton?
There were alot of people there in the early 2000s tied to natural gas industry, who invested most of their retirement in their companies, they lost it all. Also, there was a crap ton of drugs/meth there. I once saw a map of kansas where a red dot was randomly placed within a county for every meth lab found there. In SW Kansas it was mostly clear, except for Stevens county, which was completely red.
Also, Ark City always seems like a shithole when I drive through there.
