Hi, well you have all guessed what I would probably have guessed (and it is probably the correct explanation) - but here is what I was told:-
For the old fashioned pram!! (perambulator) - for the mums talking their new off spring for a Sunday afternoon stroll, on their way up Manchester Road, to Oak Hill Park - must have been an extrememly bumpy ride anyway for the poor child, but slightly less bumpy on the section near the Hargreaves Arms Pub.
what do you think about that explanation?
