I was thinking of metal bins. I remember my father used wire, springs, and hooks to keep animals out of the garbage can!
Any ideas about 2-legged predators?
My 4 girls will be temporarily moving to my school's garden. If the project is successful, we may decide to keep some there for the full school year.
I live in the suburbs, where predators are lazy and would really much rather knock over a garbage can than go through the trouble of breaking...
