Turns out it worked after all. I never wrote more than the first week in a DOC file to track costs, but I have been taking pictures all through the process. Lately I've read a lot of other build logs that I have discovered after the fact and there were things I would have done differently - had I known.
To that end, maybe this (Reverse blogging) will help. It should also make an effective backup of the work undertaken out here in the cloud.
