UpperSouthClave

USC was a series of relaxacons with a rather convoluted history. UpperSouthClave III became the first Kubla Khan. {Were USC 4–9 also Khubla?}

In 1980, UpperSouthClave spun off from that and became Concave. As Gary Robe wrote, "{After Concave 1/USC X}, Nobody else bid for the USC, so we decided to do it again. The site selection meetings have been a part of the Concave tradition ever since; to date, no other bid, either joke or serious, has edged out the Bowling Green group, and Concave still retains the USC as a subtitle."

See Gary Robe's History of Concave.
