The Metrodome went up in mid 70s. Its roof collapsed twice in the late 70s, while I was in college in Northfield. As expected when you count on hot air and the name of a liberal icon to hold anything up.
No, it was built and opened in 1982. The first collapse happened in 1981 before it opened, and collapsed 3 more times over the years, the latest in 2010.
So much for precise memories. I thought it collapsed while I was in the state, 40 miles south, but instead it did in ‘81, ‘82 and ‘83. I’d left, but was still following MN news and misdated those memories.
