Riding with a good number of our crew, such that my “audible warning” to pedestrians/bikers we were approaching was “On your left; four bikes.”
At one point, as we were passing a couple of pedestrians after giving that warning, one of the walkers said, “It’s for pedestrians, too.”
I resisted yelling back, “f o u r, four” for fear of them only hearing “f” and “u”.
