Premier1supplies.com, online, on the phone, and in their paper catalog, all helpful information and supplies. HowardE on this site is really helpful too. "Go big or go home!" is the story here; it's got to sting to be effective!

As Azygous reported, only very good electric fencing will keep a motivated bear out!
Plastic containers won't keep mice and rats out either; plan on metal garbage cans for rodent protection.
We don't yet have bears here, but that may change, and more electric fencing will be necessary then.
