If your kids play basketball, you have several options.

Join your local YMCA

With this option, your kids will get guaranteed playing time.  However, the coaching is done by volunteer coaches and can be inconsistent.  The level of play is lower than more competitive leagues.  But it can be great to introduce your child to the game, and with a somewhat lower level of pressure.

Indian Nations Basketball Conference

This league has two levels, recreational and select.  In the recreational league, the teams are built by drafting.  In the select league, you can form your own team.  Beware that in the select leage, many parents have deliberately held their kids back, so they can be quite large compared to the average kid of that grade group!
