Stripping the front took me a solid week because of all the angles, but it soured me enough to the process that I hired two transient workers from the Millionairs Club to help me strip all of the back of the house ... in one day.  The three of us on the roof and Nora hauling the old roofing material from the ground below to the 8'x16' dumpster we had in the driveway.  The next step was hauling sheets of plywood up the ladder, putting them in place, trimming them to size, and nail gunning them down.
