Check out this sweet video the guys and gals at Vice made. Very interesting. I would love to travel to the Ukraine and see this for myself. As the story goes the nuclear power plant was being mismanaged. This lead to a massive explosion in one of the reactors which subsequently lead to radioactive materials being released into the environment and a huge radioactive cloud over Europe.
Since this event it seems that the whole area around that famed nuclear explosion in The Ukraine has been more or less abandoned so the wildlife has grown back. As the legend goes, some of the wildlife has been affected by the nuclear fallout, but its extent is still being documented.
Perhaps it has created a real life Teenage Mutant Ninja Turtle.
All jokes aside, it is beautiful there, with one fan even regularly driving through Chernobyl on her motorbike.
