Skate Rats

One of the cooler things in London is the skateboarding that takes place in the undercoft beneath the Queen Elizabeth Hall on the south riverside. The skate boarders have their own thing and don't bother anyone.
Yet, they were nearly kicked out severals years ago to make way for a £120m refurbishment project.
The skaters balked, refused to vacate, and the ensuing battle with the Southbank Centre lasted 18 months. The skaters eventually won with support from the public and then-mayer Boris Johnson.
In reality, the Southbank Centre wanted to move the skateboarders 120 metres upriver to a space under the Hungerford Bridge but Lambeth council received more than 27,000 objections to the centre's planning application. 

Southbank lost the PR battle.
