@bobjonkman asks, in regards to group communication:

Q2. Does anyone use whistle codes? The sweep can whistle twice to get the leader to slow down (spreading out too far is the most common problem I see on group rides), maybe three times for a full stop.

Are there standardized whistle codes for this kind of thing?

(Or are there other nonverbal auditory codes for this?)

@ascentale @bobjonkman @bikenite A2. I never learned how to do the really loud kind of finger whistle, although I suppose I could use a metal whistle.

It reminds me of border collie whistle commands, though.

@meganL @ascentale @bobjonkman @bikenite when I was an apartment pool lifeguard I endeavored to learn to finger whistle ;) It sometimes works.
These days lots of people are carrying whistles. I like the idea for when we have an event ride. Group rides... usually separate into clumps and that is fine.
