@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 #BikeNite A2. I could whistle out Morse Code, but that would require A. bicycling with other people and B. bicycling with other ham radio people who know Morse Code. πŸ€”
