You don't seem to understand that the fan base is getting older, a lot older. The lack of parking, the walking up the Hill (yes, I know how lame that sounds), and then the general blah atmosphere in the Dome except for a handful of times per year is why the attendance keeps declining.
Blackouts aren't going to help a 60+ year old walk up that hill, and then walk up about 144 steps without a hand rail to get to their seats in the upper tier. They should have benches and oxygen tanks halfway up the upper tier.
And even on those "good" game days when the Dome is jumping, you can't walk through the hallways and can't get into a bathroom. I drink less beer than I used to at games because I had seats near the top of the Dome and just don't want to make the walk down and back at halftime to take a leak.
P.S. - I am going to the game on Friday to thank the seniors and show support for the program. But I did get seats in the lower level.
