I recall a football game, probably an exhibition game, since it was played in the Astrodome, about '76 or '77. It was raining very heavily outside, and, somehow, the runoff was leaking into the dome.
The game was called in the third quarter on account of rain!
Certainly, the Ice Bowl and others outweigh this, but I had to share this bizarre outcome.
A more recent super cold game was the 2007 NFC Championship game. -1 at game time and -23 wind chill. And it went into overtime.
Another contender:
1963 NSW Rugby League Premiership Grand Final at the SCG between St George and Western Suburbs, won by St George 8-3
The picture of the two captains at the end of the game (Saints prop Norm Provan and Wests halfback Arthur Summons ) is a rugby league icon known as
“The Gladiators”
Final score was 21-17, Green Bay
I grew up and lived 90 miles from Green Bay and couldn’t watch the game due to the then existing NFL rules banning TV broadcasts from stations within (100?? miles) of a game.
People I knew who went to the game all brought sleeping bags. I wonder if those would even be allowed into a NFL stadium today.
Announcer (I’m pretty sure) was Ted Moore.
The next season, for the pre-season intra-squad game, that 21-17 score was still up on the scoreboard.
No idea who this announcer was, probably for Dallas.
Final drive:
The 1904 Summer Olympics, the marathon in particular.
Marathon winner Thomas Hicks on his final race: “I am sorry to say that the road is the hardest over which I ever ran. I have done the distance in little over two hours and a half, but today I did my best. I lost 10 pounds as it was, and you can see that I could not push myself any faster and lose more.”
I was at that game; I was home from college for Thanksgiving, and my ride back to UW-Madison wasn’t able to pick me up, due to the bad roads. So, my father and I went to the game (we lived about 4 miles from Lambeau). It was cold, but it was the snow that made it so memorable.
Legend has it that the Bucs were trying to warm up on the field, before the game, when two of the Packers’ running backs came jogging onto the field, in t-shirts and shorts, laughing in the snow. That was more than a little demoralizing.
