Not sure what club your child plays for, but I noticed DSC has some teams registered for the Sandlapper league. I think some clubs are all in while others have only some teams entering.

I would think travel at those ages would be a concern for some of the clubs outside of the low-country. For example, DSC's closest CPL partners are CFC in Spartanburg and SCFCU (which does have a pile of teams) in Columbia.

Of course DSC is also listed as being in the Carolina Champions league (the only SC club in that US Club Pro league).

Like all new things, there will be kinks to work out.
