Today Josh was here to help again and we added some extensions to the back of the deck to fill the gap to the wall, then got to work on the OSB floor sheets. Josh had to go before it was all finished, but I managed to get the rest done by myself. I still need to get some more screws to get everything really tight, but tomorrow we should be able to start getting all my shelves and storage cabinets put up there, and start finally putting things away.
