Thousands descend on Colorado town for Frozen Dead Guy festival

The annual three-day festival - which was inspired by a Norwegian granddad who reportedly ended up being cryogenically frozen in a shed in the US state - will see attendees dress up in fancy dress costumes such as vampires and zombies.

Approximately 20,000 people are thought to be attending the festivities - which aim to encourage people to revel in the joy of being alive - over the weekend, filling up a town with a usual population of just 1,800.

Festival organiser Amanda McDonald told the Daily Mail newspaper: ''It's like a weird mix of Halloween and the Winter Olympics. There is something very Monty Python about it isn't there? Just the name - 'The Frozen Dead Guy Days.' It's certainly unique.''

The event first started in 2001, and Amanda says the aim is to ''enjoy being alive'' and help put the small Colorado town on the map.

She added: ''It's about enjoying being alive by celebrating death. Importantly it's also put the town on the map. Initially I think quite a few people were annoyed by being known for such a thing but in time it's became a great way to keep the town's businesses going during the winter months.''
