[Huntin' Ref]

Hi All - I have a meaningless question, but nonetheless it is driving me crazy this evening. In a 3-person crew, where do the U1 and U2 go to start the 2nd half? We always just fill in and have never followed any formal protocol, but I was asked about it last night and can't find it in any official manual (NFHS, IAABO, NCAA-M). Does anyone know if I am missing it in a book or just a logical thought?

We have U1 and U2 watch the same teams they watched in the first half.

Thanks in advance for your thoughts.
