I am a member of CBOA (assuming you mean Cardinal Basketball Officials Association), and to the best of my knowledge, we don't do any games in DC/MD. I think it has to do with being "sanctioned"(?) by the Virginia High School League (VHSL), and they obviously have no input to anything in MD. CBOA is somehow affiliated with one of the local IAABO boards for tax exempt purposes -- don't know the details.
Mark: You can send me several $100.00 bills anyway, and I don't even care if the serial numbers are sequential.
RecRef: You by any chance have any other info regarding this tournament?
