Not sure exactly when they changed but I noticed new plastic trolleys in Dickson today. I have my doubts that entirely replacing a fleet of salvageable metal trolleys with plastic ones (even if recycled plastics) is actually "pushing for a greener future".
How do they go when I surf one down main road though?
Now that seems like an idea for a youtube video.
