The poles were the easiest to get. Those things are all up and down the road. Just get a chain saw and a ladder, cut the top out, and leave the wires hanging and then cut the poll down. I don't recommend getting two in a row though.
The steel is made from discarded pits and pieces with LOTS of welding rods.
I had to break down and buy the 2x6 stringers. I am still looking for some steel roofing to fit that has been abandoned but I suspect I will have to order that and put it up quick before someone borrows it.
I almost have the prep work done. A local crew is to be in later in the w eek to set trusses and install stringers.
