We have to replace it, if anyone stepped on it their foot would go through. So had to run down to Marella's (40 minute trip) to get Jaeger's RotoThing tool, chat with them (30 minutes), come home (40 minutes), pick up spare bits and plywood at HomeDepot (20 minutes), come home and fuck around with testing the tool and making tiny baby cuts in the floorboard (1 hour).
