I try to take my garbage cans to the curb during the daylight hours. That way I can see any spiders that might be lurking on the handles (and I've found quite a few, so my fears are warranted!).
But I would have to add a kevlar vest, a welder's shield, and butcher's gloves to my routine if I had to contend with the coconut crab. I can't get enough of these monsters. I wonder if they make for good guard crabs. I'm sure they need less attention than a dog.
UPDATE: I have spurned one of my readers, for which I must apologize. Frigga had linked to this image in a comment on my original coconut crab. I am sorry, Frigga--I hadn't seen that link. (This is me giving you the credit you deserve!).
