Why?!? Because it showed that there is no point in spending the $$$ if the team and fans etc. are at the whim of the weather and have to worry about whether a game (or other event) is going to go forward EVEN IF the roads are cleared. [i realize that it took time to clear the roads, but there was a question about the following game against Cleveland even when they had made progress with the roads - it seems odd that we would be dependent on how many snow shovelers would show up to shovel a huge stadium].
I have been going to that stadium since 1972. I have season tickets and have kept them even though I live in Miami. I have been to games where the conditions were miserable even almost getting frostbite on my feet at a Jets game back in the 1980's. I have no problem going to games when it is cold -- up to a point. I find very little romance, however, in going to a game when the rain is horizontal etc. I have no problem with a retractable roof that would close when the conditions are miserable.
It just does not make sense to spend the $$$ on a new stadium if you cannot use it more than a handful of times or people will not go because they would rather watch the game in their family room. The big screen TV and family room are the real competitors for home football attendance. That is just a fact. We can choose to be romantic and all say wouldn't it be great to sit through the ice bowl even though we have had hard times selling out games in December -- even when the team was very, very good. Hell, the comeback playoff game against the Oilers was not even a sellout as I recall.
The fact remains that it makes perfect sense to have a dome/retractable roof downtown not only for football games, but so that it can be used more than 8 or 10 games a year.
