Mountainside

The town nobody knows about but is secretly rich because of its low taxes since it has no highschool. Overall Mountainside kids are pretty nice and innocent until they go to Governor Livingston High School then they start doing drugs, partying, and buying designer items (gucci belts) unless they go to ucvts and just become nerds. Also is a very white and republican town with lots of trump supporters, few asians, and very few hispanic or black people. Mountainside is a beautiful town though with lots of trees and nice houses although it is very hilly.

I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
