TL;DR: Loads of people dressed as Father Christmas for no apparent reason
Here's the lowdown... SantaCon is a non-proﬁt, non-political, non-religious and nonsensical Christmas parade in which hundreds of people take to the street dressed as Santa.
Nothing more and nothing less. It is, er, celebrated in a bunch of countries all over the world in mid December, it's totally bizarre and not everyone is a fan.
Whether you think it's stupid or not, you still want to see pictures of it right? Right...
