A small, quiant little town in the San gabriel valley in California near Pasadena and Monrovia. The most BORING city in the world where nothing interesting happens. Filled with conservative white old people who take care of their grandchildren and take them to a nice little park, with a beautiful view of the local cemetery 50 feet away from the swirly slide. Sierra Madre-ians always leave Sierra madre if they want to have fun (usually the unfortunate 1% that are teenagers that live there). They go to pasadena (Old Town, Paseo Colorado) or Monrovia (Westfield Mall) to enjoy themselves and wish that they lived there.
Jim: Hey lets go chill somewhere fun.
Bill: We can't drive, and where stuck in Sierra Madre.
Jim: Shit, i wish I live in Pasadena.
