Ottawa's streets were alive with hundreds of undead Saturday as the sixth annual Zombie Walk haunted its downtown.

It was a day where seeing splatters of blood along Byward Market sidewalks and businesses and grey-faced figures dressed up as tennis players in front of the American Embassy was a little less alarming than normal.

Some of the crowd of devoted dresser-uppers went all-in by foregoing words for grunts and moans, while others were a bit more coherent.

"We just feel so pumped," said Natasha Boulanger, who has been dressing up for the walk for two years. "It's great to see everyone's reaction to everyone."

"I decided to go with a zipped-up zombie," said another participant. "It's a lot of time, a lot of effort."

The walk started at McDonald Gardens Park, a former cemetery where organizers collected donations for the Ottawa Food Bank, and ended at Parliament Hill where an unsuspecting couple was getting married.

A likely awkward meeting between a zombie Moammar Gadhafi and a group celebrating the fall of the dictator's regime on the Hill was avoided.

The walk included a mobile model coffin where people could get an idea of what it would actually be like to rise from the grave.

"It's better to try it before you buy it," said its owner Casey Canning.
