There is no one classification for Bigfoot. Some are quite curious and others seem to be aggressive. Many factors play into what a Bigfoot might do. The vast amount of the sightings we get are of a curious non- aggressive animals. But, I also get the reports of Bigfoot causing injury to folks from time to time. This is really nothing new; many stories throughout the years tell of violent creatures.
The creature or mountain devil Teddy Roosevelt spoke of on the Salmon River was anything but friendly.These are mostly bigfoots that have been shot at in the case of Ape Canyon and the Bauman Story (Roosevelt Story). I interviewed the Ellisons and found no reason for the animal's behavior, other than hunger that drove this animal to do this.
The Sru lake story is the same. The Hamiltons were cooking supper at the time of the encounter. Also another disturbing fact about Bigfoot is they seem to like to get too close to young children, especially young girls. This is something every parent should be aware of when camping in the forest. 99.9 percent of the time the Bigfoot simply is curious but then we have that one tenth of one percent that is dangerous to people.
When people are in the forest be aware of your surroundings and take extra caution with young children.
