The Pump Cage is the mini skate park under the Mancunian Way to which skateboarders where exiled a few years ago because they dared to use the city centre for interesting things other than spending money. It sounds like it’s been more successful than I expected and now it’s won funding for lights and a power supply for the on site office.
I still think skating facilities should have been provided closer to the centre, but good for them anyway.
