I camp in Wisconsin and I use that method too. I keep all my food in a plastic bag which I then put into a silnylon bag. (Ideally the silnylon bag you use can be hung so the drawstring opening faces down, remember rain water will travel down the line, so make sure the bag's opening won't collect it!) Then I do the PCT hang using parachute cord. Very simple.

Sometimes when I'm weekend travelling with people and we are dividing the weight, we'll use a small bear canister: BearVault BV-250 Solo Bear Resistant Food Canister, just for the convience of not having to hang it.

But I'd recommend the PCT method. All your practice will come in handy for other trips to bear country!

Hope that helps!
