11-12s -- NorCal division 2 official tournament site: Web Link
10-11s -- California District 4 Tournament resources (District 4 is hosting the NorCal Division 2 tournament for this age group). Click on the link and then click on "10-11 Year Old BB Schedule." This site is pretty confusing! The Schedule page leads you to download a .PDF with the schedule. Web Link
For directions to the 10-11 site, you'll have to click on the second link on the District 4 page, "10-11 Year Old BB Division II Letter." Not exactly obvious.
Best wishes to both PA National All-Star Teams!
