Something primevally chilling about hearing packs of wolves howl. Even more so in the dark when all you have for shelter is the thin fabric all of a tent. Yet, it is strangely compelling and raises the desire to hear it again and again.
Some of the first videos it appeared that the game camera must have made some kind of noise or such.... both a wolf and a moose came over to examine it.... or maybe it just smelled of human?
