If you want to know what heat in general felt like back in the 1980s, when there was still real heat, then watch this match. There is more heat in this one match than in a year of Raw all added together.
Not sure of the date of this match, but it was sometime after March 8, 1986 (when this version of the U.S. belt made its debut) and when Magnum was stripped of the title in early June of 1986.
I think this is Greensboro, but there again, not completely sure. But that looks like Wally Dusek at ringside with Tony Schiavone so I'm thinking Greensboro. However, Tom Miller was usually ring announcer for Greensboro, so this may be Charlotte. Who knows? Who cares? It's awesome.
