Spent a large part of the day helping Viv Schwarz with her carboard maze at the Sandpit event at the National Maritime Museum. Lots of fun, though I realised I’m not as young as I used to be – after about an hour and a half lifting and taping and so forth my back and legs stiffened up and I spent the rest of the time hobbling a bit. Took both cameras – the good one to make an “official” movie and the cheap one to make the diary entry. Eventually, the staff are waiting for us to pack up and stuff the cardboard into a cupboard for disposal tomorrow (amazing how much corrugated cardboard you can stuff into a cupboard if you put your back into it. Hope someone warns whoever-it-is before they open the cupboard tomorrow morning). Catch a train and home very late indeed.
