Both the WCRHL and ECRHA will be introducing 2 new Division III schools each this year. WCRHL will add Santa Barbara City College and Orange Coast College. ECRHA has a post on their message board talking about their 2. I can only speak of the WCRHL, but both SBCC and OCC are VERY talented, having players with much tournament experience, and should likely give any DI school a run for their money.
