Greeley, Colorado is famous for hardly existing. The college or university or whatever a nitwit might call it is so far below Mediocre, it's classified as an 'advanced kindergarten'. Nothing else exists in the city except drunks and child molesters. Zombie-fied citizens, the living dead, where you go other than Hell, the ultimate cess pool!

In the Lego online community, greeblies are the intricate details on the sides of spaceships and sci-fi MOCs that define the mechanics and workings of what the MOC is meant to be. They were famously used in the giant Star Destroyer Lego set a few years ago, and also in the more recent Death Star II set. Plates with rails are often used for greeblies because they have a protrusion that only sticks out half a stud without needing a jumper plate. (source: Brickspace.org)
