Welcome, Well I cant speak for the rest of Canada but here in MB. We have had an even called survivor. The first one which unfortunatly I was not as much a part of lasted a week, and the second which I was out for the entire time was 3 days.
Those events last the entire span, where a few individuals usually around 5. Stay out in the forest the entire time, the rest of the community is welcome to stay out and hunt them down continually whenever they want. The experience can be alittle nuts as you are constantly on alert.
I cant take credit for the creation of that OP but I really enjoyed being apart of the second one. The nights were abit nuts especially when it was completely dark.
