California High School League Rule for outside competition.The State is split into two regions so the SoCal soccer players cannot play club during their interscholastic season which is played in the winter in SoCal. Now that state produces some very good soccer players don't they?

ARTICLE 60
OUTSIDE COMPETITION
600. COMPETITION ON AN OUTSIDE TEAM
A student on a high school team becomes ineligible if the student competes in a contest on an “outside” team, in the same sport, during the
student’s high school season of sports (See Bylaw 511). The following exceptions apply:
A. If the outside team has half or more of the team members as stated in the National Federation rules book for that sport, it shall be
considered the same sport. Examples: three on three basketball---outside team competition prohibited; two on two volleyball---
outside team competition permitted.
C. SOCCER
In the sport of soccer, Bylaw 600 shall be in effect only during the winter high school soccer season. High school soccer
programs that compete during the fall or spring season are not subject to Bylaw 600.
NOTE: For purposes of this section, indoor soccer and futsal are not considered the same sport.
