Everbearing is right

Today seemed like a good day to plant garlic in the strawberry bed. Believe it or not, those everbearing strawberries are still bearing. Not a lot, mind you, and we haven't had a killing frost yet (maybe tonight), but still at it.

Does this look like a good idea? (Photo from somewhere else.) I'm intrigued by the concrete block part, not so much the 2x4 bit. Not sure where I would locate such a planter, nor what I would put in it. Herbs?

This critter was my 17th Trick or Treater last night, the final one.

From Wiki: "The banded woolly bear larva emerges from the egg in the fall and overwinters in its caterpillar form, by allowing most of its mass to freeze solid. First its heart stops beating, then its gut freezes, then its blood, followed by the rest of the body. It survives being frozen by producing a cryoprotectant in its tissues.[5] This freezing occurs outside of body cells, but not within. In the spring, it thaws."

Isn't nature amazing?
