Cesa Spartanburg is part of CESA proper (Greenville). Kind of hard to put two club affiliations on one club. Cesa Columbia the best I remember had to be a different club to get around the dumb SCYSA anti area crossing rule.
To date there were a lot of fears about the CESA Spartanburg thing, but the guys from Greenville have done everything they said they would, so far, anyway.
