The Vexillological Trainline is a flag arrangement from national to the ultra-micro political level. Officially speaking the township/city/borough flag is the lowest political level of the US. But below the township are several more personal levels: the Quadrant, Blockship, Hutship and Partship.
Here we have a map of the world with two Vexillological Trainlines showing two "Engine to Caboose" flags from the personal ultra-micro political level up unto the national level. On the West Coast by Los Angeles is the Vexillological Trainline of a fictional character from the Big Bang Theory Show. On the East Coast is the Vexillological Trainline of a friendly neighborhood blogger.
As Pasadena is a part of Los Angeles Metropolitan Area so too is Lansdale a part of the Philadelphia Metropolitan Area. Likewise the Rose Bowl is renowned in Pasadena, just as the Army vs. Navy Game is best known for being played in Philadelphia; as this was the city where the official US Army and US Navy were created during the 1776 Revolution. Likewise a good match for Caltech is the University of Pennsylvania.
To quote Joseph Ridgeway Grundy, "If a man does not have pride in his own hometown, he isn't likely to give a rap* about his own country."
