apparently that huge mouse i rousted out of the front-center middle bed had made herself absolutely at home in my garden. i accidentally uncovered a nest this morning; at least three baby mice tumbled out as i was weeding. i put them back as best i could, and tried to softly pack in some dirt and plants around them. they had fur already, but their eyes weren't open, so they have a couple weeks of nursing ahead. i hope she comes back, and that they get it. i can put off working on moving the raised beds until then.
in fact this may solidify my decision to add two more raised beds in the direction of the shed. :)
