See CT's eligibility rules: https://www.casciac.org/pdfs/eligibility_brochure.pdf essentially, you cannot participate with an outside club team AT ALL in season! I don't know about you, but travel club practice definitely starts before the school season ends, and even some tourneys may be scheduled before then! I realize this on the SA side, but CT appears to have worked both sides of this equation to kill club as best they can.
