Periodically I try to play the word peloton, and every time it fails to be accepted, I make mental note to myself to request its addition to the Chihuahua lexicon. Such an occasion occurred last week, but my mind being what it is, the note failed to stir any action until today. For those unfamiliar with the word, it is the main cluster of cyclists in a bicycle race. RF also refers to clusters of cars on an expressway as pelotons, which is where I first learned the word.
