Late yesterday afternoon, HP called me from the ELC about her class today, in Lab B. She wants to show a video. I checked the TV cart in Lab B this morning, and it has no VCR on it (has it been stolen, or was it never there?). I decided I'd move the one from lab C, which is set up and working, but the cart has been padlocked to one of the desks, so that's out. There is another TV+VCR cart in the materials room, so I've rolled that into Lab B in the hope that it will work.
