As any graduate of Penn State (main campus) knows, Philly and Pittsburgh are like night and day. Scranton/Wilkes Barre has its own flavor. So does the Erie/Edinboro area. State College/University Park is a melting pot - but most come from near Pittsburgh (about 1/3); Philly (about 1/3); and (Jersey/New York and the remainder of the world the other 1/3).
Unlike states likes Kansas, Iowa and Nebraska ... etc. - which are all pretty homogenized (i.e., standardized). Pennsylvania has stark differences in the character of their citizens - much diversity.
The extremes start with:
(1) the Amish (i.e.., Pennsylvania Dutch) where whole towns build barns for a neighbor and ride buggies;
(2) then you have Pittsburgh - a working class city that shifted gears from blue collar to high tech ... a place with class and homes with signs hung on walls that say "Welcome Friends" - much like being the eastern edge of the midwest; and
(3) Philly is epitome of east coast bitterness, acrimony, venom, selfishness, spite........similar to New York City folk but more insecure - and similar to many Bostonians .... but with less intellect.
As one from Western PA who spent 4 years at PSU and 18 years prior growing up in PA - I saw the stark differences in Pittsburgh and Philly folk. Anyone who has experienced the difference will tell a similar story.
Moving on, I've lived in San Diego for the better part of the last 18 years. REPEATEDLY, Charger players have complained that in the San Diego Union Trib that home games against the Steelers seem like AWAY games. SD WR Anthony Miller was the first of many I noticed to ##### about it - and he and I talked about it at the Pacific Princess Resort over a few beers.
I've been there for the number that have taken place at The Murph/now known as the Q. Steeler Nation takes over the tailgates and the rest. It's epic. All the Bolts backers trip out when their own turf gets "eminent domained" by the 'Burgh.
Also , near the beginning of this thread - I noticed a fellow San Diegan mention an ear-biting event pre-Tyson/Holyfield involving the Raiders/Chargers rivalry. Unless this lunacy is more common than I'm aware of, I have a very good idea I know exactly what event he was talking about. In the early 90's at a sports bar known as "First Round Draft" located in the Ocean Beach area of San Diego - a Raider fan bit off a Charger fan's ear.
Good to be passionate about one's team - but go easy the ear chomping.
Lastly, the reason Pittsburgh supports the Steelers is a simple derivative of the fact it's a FOOTBALL TOWN. A city like St. Louis or Boston are baseball towns. That is where their true passion lies. Kentucky and Indiana love college hoop. Nebraska loves college football. Some regions are gung ho over NASCAR. But Dallas, Houston and the entire state of Texas - and Miami and the entire state of Florida are into FOOTBALL. Pennsylvania is the same way. It's a FOOTBALL state. If the Pirate or Penguins fare well, we get jazzed - but it's all about FOOTBALL.
