While this isn't rosy, this entire post really couldn't be a more accurate assessment of where sufb was and is.
Game day and tailgating atmosphere, while I couldn't be happier with the North Manley family for decades now, most casual fans don't find it very appealing with parking and walking (my kids and I are gym rats, so we are the definite exception) so far to get to the Dome.
And yes, most of the fan base you mention is long gone, most of the big industries and businesses (carrier, GE, electronics parkway etc.), all closed or moved in the 90s. Ppl moved away. And that generation of ppl, who are left, is smaller every year.
Add to that the well known alumni problem (most students are not from the NE, prefer pro sports, don't go to games as students, and never grow much attatchment to a program that has been mediocre at best for decades, and those that did, live far away and rarely come back to games), a lack of local casual interest unless it's an 'event' game, and we are what we are.
We are all bleed orange diehards, but the reality is su is a difficult program to have long running success, for the myriad of logistical/fan reasons we all know and discuss on here ad nauseum. Its why we all get so excited when we think maybe we can have nice things for a while around here.
Can't wait till Ohio.
