JRutledge wroteI say this because you do not do that during quarter breaks or halftime and don't they go the right way then?
I've got my whistle in my pocket, and I look at the team color on the benches (knowing that I must also know what half we're in). I know a lot of you guys don't like that (pocket whistle), but it's a "When in Rome" thing around here, almost mandatory.
At the horn ending the second period, my partner and I meet at the division line, opposite that table, and wait for the benches, and lingering coaches, to clear. Then we head toward that table, switching our pocket whistles, and we say to each other, "White to start the second half", and then the referee repeats this to the table, and has the scorekeeper switch the visible arrow.
