I attended the first one at the Silverdome on Dec. 6, 1980. It was an invitational event called "Heroes vs Outlaws". They ran the heats in the afternoon, cleared everyone out, sold a separate ticket for readmittance, and then ran the features in the evening. If I remember correctly, Rich Vogler turned down an invite because they didn't also invite his father, Don. I will have to do some research, as I don't remember who won the feature. I have a program from the race, but it is rather inaccessible now.
