I have hung my 30L barrel before. I was quite proud of myself, having mastered a simple pulley system to hoist the heavy tub aloft. Well away from the ground, tree trunk and branch. It was perfect. Each perfect hang I nearly never wanted to bring it down; I'd taken some time to get it just right. But after struggling on some trips to duplicate the perfect barrel hang every time, I eventually gave up. I started practising the stash. Sometimes 30 yards but usually more from campsite, under low low living branches, often close to shore. If need be I tuck in an added hemlock or spruce branch I've harvested elsewhere, though that is seldom needed. There are lots of fir trees with ground hugging branches to choose from. If not, I walk further from camp. I tie the barrel to the tree, and yes that is awkward. Stainless carabiners are left always attached, hopefully to jangle enough for us to hear 30-100 yards away. (That is why I don't want it too far.) I don't use any kitchen pots as a warning system, because I can't be certain they're perfectly clean enough not to act as an attractant. The barrel is kept scrupulously clean. Even if I were hanging, that is always absolutely necessary. For that reason alone I've altered our tripping menus somewhat, and all food is watched and contained at all times. My food exploration with dehydrated is as much about it all keeping cleaner and contained, as it is about simplifying prep and weight/volume issues. It's usually just us two, so I go way OTP in this regard. Kitchen is cleaned up entirely before the both of us so much as wanders off to do whatever chores await us. We've started bringing along bear bangers, mostly for peace of mind I suppose. All this sounds @n@l to northerners I know, but we started our tripping lives in Algonquin PP, where the occasional problem animal comes to call it seems. I, like most animals on this planet, am a creature of habit. I'm making it a habit to leave no trace, especially around the camp kitchen. It takes practise, like anything else. I'm only deluding myself to think I leave no scent trace, nor crumbs of food anywhere, but if I can prevent even one wildlife encounter in camp, then it will have been worth it.
