Two bags of trash left (mostly from the closet and the pile on the floor), along with a bin of recycling (mostly from Christmas), and we swapped the treadmill and chest of drawers around, making the room much more accessible, even when the treadmill is down. We hung a couple of pictures, found the missing wedding photographs, and just overall improved things.
We've still got to put the mirror back onto the dresser, but the first two sizes of screw that we bought weren't quite right, so it's back to the hardware store tomorrow. (The original screws have vanished. Fancy that.)
