I'm logging all my time on the '51 3100 restoration on a spreadsheet (I started out manually in a notebook), including date, what I worked on, and how much time was spent. I'm real close to 1500 hours now.
I also have a spreadsheet of every part I've bought so I can refer to it when trying to remember if I have the part already. (It's been more than once that I bought the same item again when I couldn't find it in the box.)
I also have a fuel mileage spreadsheet for my daily drivers, logging date, gallons added and mileage between fill-ups. That one also shows me current and lifetime mpg and a running average of mpg over the previous 4 fill-ups (helps see if something has gone wrong.)
After the EMP happens, I have a pencil and notebook.
