 You can see the front wall of the workshop at the left edge of this picture.





I was lucky and found the better part of a large tent frame in a junk yard. I used 1-5/8" commercial fence piping to complete it. It is 19' at the peak, 18' wide and 50' long. It has rained nearly everyday this month, man am I glad I built that frame
