What eyesore makes you sore?

Blots on the landscape—They are everywhere. Junk cars rusting into a pile of parts but parked on a city street or the neighbor’s dead lawn. The alley in a city center that has somehow degenerated into a collection point for wind-blown trash and human detritus and never gets a visit from the street sweeper. The dilapidated home with peeling paint and falling gutters, slowly reverting back to nothing but soil, but unfortunately not doing so within our lifetimes. What’s the pet visual peeve in your neck of the woods?
