In all the threads I've read about sheep hunting here, I haven't seen anyone mention how they deal -- if at all -- with keeping their food from causing bear issues. I also haven't seen bearproof canisters on any gear lists (even though they're required by law for backcountry hiking in some places). They certainly add a lot more weight than you'd like.
Also, in all the tips I've seen about keeping food safe from bears, I haven't seen anything about what to do when you're way up above treeline and don't have trees around to hang things in.
So, what do you do when hunting up in the alpine tundra? Just carry well-sealed food, burn your trash, and not worry about it? Store your food 100+ yards from the tent every night?
