I have been in the backcountry of MT and have seen two different grizzlies on the same day. On another day I ran into three piles of grizzly scat within 15 minutes. I didn't care if there were 400 class bulls in there, I started making noise and left. I've read that 70% of grizzly attacks happen to bow hunters hunting elk - very nerve racking when hunting solo. Then add wolves in the mix.
Last year I bugled at sunrise on a ridge top, had a pack of wolves about 3/4 of a mile away immediately respond with howls. Within 7 minutes they were below me about 150-200 yards away howling in a pocket of timber. It made the hairs on the back of my neck stand up!
This is my first year hunting in coastal Oregon, and I enjoy not having to worry about wolves or grizzlies.
