I hear what sounds like a whistle. That does not sound like any shoe squeak I have ever heard. In a loud gym shoe squeaks don't stand out like that. I suppose I could capture the audio, run it through my frequency analyzer and compare its pitch to that of a Fox 40 whistle, however that process would be fraught with error.

I am wondering why the Trail points to the Lead, and then to the bench? What is he trying to do there?
