I got a couple Bear Vaults... Kind of pricey I know. But my experiance is there is a lack of good trees to hang your pack high enough. And some places... forget it, your not hangen nothing. I had a pack made by a friend and hope to employ this settup this year. I know there is a bear that can open the Bear Vault in New York I think, but chances are I'm good to go. Also, not as much room as a food barrel, but your going to pack lighter this way too. I'll let you all know how it works...
