About SuperClash, it would not have been unusual for a PPV to be held on a weeknight at that time. ChiTown Rumble was on a weeknight a few months later. It probably had more to do with ensuring they could get TV taped and distributed for the weekend.
I lived in Waukegan,Illinois then. For point of reference it is an hour north of Chicago/hour south of Milwaukee. Our cable system at that time didn't carry the AWA syndicated show. I am not even sure they had a show in Chicago. The AWA in of itself had pretty much disappeared from Chicago for a couple of years going into this show. So we had to rely on the World Class show or the Milwaukee AWA show to follow the build up as ESPN was erratic.
