Just thought I'd post the address of the outstanding kids rec league in my area that I was associated with for about 20 years. You might want to check out the page for officials on this site. In any case, usually about 1200 kids play in this program. It's a non-profit run by volunteers.
If you have trouble with the address, just search for Tigard Basketball Association with your browser.
