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.
