I'm not aware of any, unlike some of the Rocky Mtn. Parks with fairly specific rules and regs on these matters. 

Read any of Cliff Jacobson's books and you'll see that he suggests stashing the food of in the woods, on the ground away from camp in a Canoe Pack.  (Evidently mice don't inhabit Cliff's world).   ???

Most of us here are probably 'hangers', with elaborate and cunning systems utilizing pulleys and mechanical leverage -(though some of us believe that Hope is indeed a strategy and simply leave food in camp with a pot balanced on top of the food pack). 

I think if you use a vittle vault and place it away from camp on your solo trips your granola bars will be safe.  That's more or less what I plan to do on future solo trips, especially since I forgot my food hanging system up on Insula last September.

If anyone found it, please feel free to call - big reward offered!

As long as, when storing the canister for the night, you cinch up the straps real tight, so the bear can't easily slip it over its shoulders...you should be fine.

The Beaver

I've done 5 solo's in the past 3 years, and I always pack a bear can.  I can easily get 5 days worth of food into it. I stash it away from my camp, usually under a log or something out of the way. Never had a problem, and it's easy to get to my food. Hanging always seemed like such a pain, and finding a good hanging tree can be problematic at some campsites. The cans are too big for a bear to get it's jaws around, and there is nothing that would allow it to be dragged away. Making sure it wont get rolled off a cliff or into a lake is your only concern. I always vacum seal my food which cuts down on odors and I've found that a Reynolds Oven roasting bag makes the perfect can liner.  I turn it upside down to prevent moisture from creaping in around the lid seams. I keep a washer the size of a quarter with a hole in the center on a leather rope around my neck for opening the can. For longer solos, or with my wife along I carry two and have numbers spray painted on the outside so I'm not constantly opening the wrong can.

Cliff's idea would be great IF people did that instead of the reverse or worse. I KNOW how that goes.

I hang because it works better and is easier than hiding for me IF the campsite warrants either. Some approved sort of barrel sounds great. Really great. No worries beyond it being pawed into the lake which only affects you, not the people who follow you.

The blue (no problems/mice yet) barrels scare me. My $3 RubberMaid food pack is blue (mouse proof) and I hear (You need to Login or Register to view media files and links). (see: Facts>Vision) Plus, I know how lazy and lucky people THINK they are...

On my last trip (4 people, 11 days) I used a combination approach, 4 Ursacks and one bear canister.  The Ursacks keep bears (and other critters) out, but are subject to being crushed.  So the Ursacks contained all the stuff that crushing would not hurt which was most things (rice, dried hamburger, etc, etc).  The canister stored anything for which we wanted crush protection (oil, syrup, etc).

Ursacks are nice because they are light and they decrease in size as food is consumed.  Bear attacks are rare (I have been fortunate to never experience one), so as long as the Ursacks protect my food from loss, risking a little crushing is a gamble I consider worth taking (risking total loss by hiding is not a gamble I am willing to take).

Now Ursack sells a liner that provides crush protection as well.  But I question if the liner is worth it.
