text: yes I know there isn't always a sign.  but in this case a passerby who lived in the area said he had not seen a bus in years, and the cambridgeshirebus site (which includes all operators) doesn't have it, plus it's rather rare for bus operators to go into cul de sacs - I wonder if these stops date from a time when the road layout was different?  anyway it would be helpful to take them off because my wife was in great discomfort and we walked from Histon Road to Sunset Square in the hope of getting a bus sooner only to find nothing.
