I like to feed birds. I keep my sunflower seed on my deck in a galvanized steel trash can with a steel lid in order to keep squirrels and such out of it. Last year, the raccoons figured out how to pry the lid off. I secured it with a rubber bungee strap looped through the side handles and the handle on the lid. Now the damn raccoons have figured out all they need to do is chew it in half and they're in. They've done it twice this week. This morning we woke to a mama and baby 'coon feasting in the can. This time it's personal. I'm thinking a chain of some sort. Chew on that.
