Work colleague just returned from a holiday in Canada.
Telling us about the rubbish bins in this Canadian town. Massive steel bins to withstand bears and raccoons. To put in your rubbish, you have to reach into a small opening and release the latch which holds down the lid. The idea is, the opening is too small for a bear's paws and too high off the ground for a raccoon to reach.
Now this is unverified - it may be true, or it may be a tall tale spun by a local to impress the tourists - but the story goes, locals have seen bears and raccoons working together to open the bins - the bear picks up the raccoon and holds him up to the opening, raccoon releases the catch, bear lifts the lid and they share the spoils!
