iPhones... decades ago in Boulder Colorado I thought it was absurd that they had police ticketing people with headphones on the bike path... now?
the audible warning is erased by the use of headphones
I am less likely to get an "on your left" to those with headphones
try not to buzz the tower... that is not my style
yet for some reason these people with headphones are often spooked
great randomness from 2006
messengers... advocates... people on bikes
