Bears and Your Food

From the New York Times: Bear-Proof Can Is Pop-Top Picnic for a Crafty Thief.

My two favorite quotes:

• "But wildlife officials say that Yellow-Yellow, a 125-pound bear named for two yellow ear tags that help wildlife officials keep tabs on her, has managed to systematically decipher a complex locking system that confounds even some campers."
  
• "BearVaults, one of several canister brands, are favored by many backpackers because they are light and can be opened with bare hands; most others require a coin or screwdriver."
