lunghd,
It is interesting, the prepositioning and 3rd arm techniques we come up with for a one-man show!?! That's why I hire inexpensive 'day' labor from time to time to be a 3rd arm. Even if they are idle more than I like, a second person keeps things moving...
Thus, the folks that did 'barnraisings' in remote areas with large groups of people were quite smart. I participated in a 'church in a day' project last year. 30 x 80. With slab foundation laid, all walls laid out, trusses and all materials on hand, a very large group started at 6AM Saturday, we were roofing by noon, inspected by 6pm. Had church Sunday morning. All that was left was baseboard (not on materials list) and exterior landscape. Considerable planning for materials and people made this possible. -All power for compressors and power tools was supplied by several gensets...
This is an example of what could be done in Wyoming amongst friends. Cash, PIK or barter services for skilled trades as necessary. Excellent technique for remote locales, such as Colonial Shooters spot.
