I'm certainly hoping to avoid getting that close to bears in any and all situations - met one up close and personal in New Hampshire a couple years ago and that was close enough for me!
Thanks everyone. I've got most of the items nailed down, only two real outstanding questions:
1) Tripod - I've read the tutorial on the site about tripods in general, and done some research on my own. My concern with a monopod was only using it in this specific instance, where a tripod seems to have more versatility. I've been looking into the options, so that should be licked in a little bit here.
2) The bag - as the list of needed items has grown, especially the things that didn't even occur to me till afterwards, we've out-stripped the size in my current camera bag. Since I'm going to be doing a fair amount of traveling, via plane, boat, and ultimately foot, I was thinking of a backpack-style bag that would have enough space for all my photo equipment, laptop, etc.
Does anyone have something like this
