Also---there are now more "transplants" from other parts of the country living in and around Pittsburgh than ever before...
Not saying there are many southern Californians living there...but when I lived in the Burgh, everyone that lived there were true blue multi-generational Pittsburghers..
Now when I visit, I meet people that have moved there in the last 5-10 years from all over the U.S>
In fact, the young couple that bought the home I was raised in, and my parents lived for 50 plus years was purchased by a couple from Iowa.
BTW---not saying this is proper, right, or what should happen....but if what happened yesterday with the Niner crowd being loud/boisterous, and that happened in the 70's...well then again that wouldn't of happened in the 70's lol.....
3 Rivers and that fan base were very intimating..
