In 1972 I put up a small poll barn/shop, 24 x 32, with used telephone poles, sawed into 10 feet or so, and used beams across poles and joists and rafters from the old cattle sale barn in Marietta on Powder Springs street. I got Mr. Marsh in Kennesaw, sawmill was downtown Kennesaw, to rough saw some 2 x 6's to go around horizontally top and bottom of poles and 1 x 10's, and 1 x 3's to put up vertically for board and batten on the walls. I just re-roofed it this past Sept-Oct with architectural shingles. I also put in two sears metal garage doors. This is a pic made in 2013 with silver truck parked on oil change rack.
