KHTS is everything we've come to expect of Verticalsim in 2023/2024. It's a well-modelled little airport — both airside and landside — with some great detail and pleasing terraforming. The inclusion of the Catlettsburg oil refinery on the approach the RWY12 is a welcome addition. Add the fact that the airport is in a rural and very beautiful part of the USA, and you have a decent package here. However there are two reasons I can't award 5 stars: the first being the very limited and rudimentary terminal interior (an area in which Verticalsim seem to have regressed lately). I can understand the performance benefit this might offer at smaller airports but Verticalsim's own Provo features one of the best interiors I've yet seen, and is a larger airport. The second reason is the slightly high price for an airport of this size — at this price point, I'd expect a more detailed terminal interior.
