I've heard a little about bear fences, are they easy to get? Did you see any cow moose?
You can buy them online, but we just borrowed a battery powered horse fence from a friend. It ran on 6 D cell batteries and is supposed to be able to run for over 5 weeks on them.

I know my buddy grabbed it once and it was either in-between shocks, or his rubber boots insulated him, but he didn't get shocked. It was pretty damn funny to watch. I expected him to hit the ground.

We only saw 1 cow moose and it was on a lake near camp as we flew in, but never saw it after or any others to speak of. It was pretty weird and unusual from what we had been told of the area, we expected to see a lot more critters.
