This isn't meant as a slight upon the people who live in trailer parks. From what I understand, the rent in some of them is pretty darn cheap, and inexpensive rent would be a shiny thing for me right about now. But with a very few exceptions, the trailer parks around Moscow area are pretty sketchy, rundown, and oh yes, odoriferous. What's interesting is that this nasal assault is immediately recognizable even outside of its normal context. The other day, while driving the hospital's bus around, I had to take two people home after a surgery. Upon meeting them, I knew by smell that they lived in one of the area's trailer parks. Not which park, mind, but one of them.
No, I am not familiar enough with Moscow's trailer parks to identify them by smell, and God willing, I never will be.
