NFHS End-of-Period mechanic

around here, we are told the exact opposite - do NOT whistle at the end of a period. That's why there's a horn. No need for it. Also, don't whistle after subs come in or usual delays, unless you absolutely have to get a partner's attention or something unusual happens.

We are taught we need a whistle and it's the trail's responsibility.

You're also in Ohio, where the football officials are required to take their books to the field.
