In a northern city like Edmonton, winter warriors have to do what they can to keep the cold days interesting.

So how about a good old-fashioned snowball fight, with hundreds of complete strangers?

The Make Something Edmonton project is called #yegsnowfight, and aims to stage the largest snowball fight the city has ever seen.

More than 1,500 people took part in last year's impromptu battle at Kinsmen Park.

Robin Mazumder and Jeff Chase came up with the idea after they both came down with a bad case of the winter blues.

"It was snowing and it was November and so the spirits were a little a low," said Mazumder. "And I think something like a snowball fight gets people excited about winter again."

The pair underestimated the city's love of a good friendly fight when they started promoting their plan last winter. They thought 50 people would show up for their inaugural event.

"But within a couple of weeks, we had like 2,000 emails from people, so it really snowballed."

Another event is being planned for this winter but, just like last year, the details will remain under wraps until the last minute.

People who want to participate submit their phone numbers to the organizers.

Then, when the time is right and weather conditions are perfect, those on the guest list will get a message with the location and time.

For the first time, a sister event will be organized in Calgary, and the organizers hope to channel the natural rivalry between the two cities.

"In a friendly competition, nothing like the battle of Alberta between the Oilers and the Flames, we want to see what city can get more people out and get more donations for their respective food banks."
