I will be flying in for a caribou hunt in unit 20 and wondered if I will need a bear fence. I read reports that some of them sound like a predator call and I don't want to attract a bear. I could also use advise on what rain suits seem to hold up in the Alaska brush.
I am planning on using a .270 for the hunt and was curious if would be a large enough caliber if for interior grizzly bears.
Any help would be appreciated.
