That was a big fat fail

not talking about booby traps here at all, but got an old shed nearby?

i was walking the perimeter around a non disclosed building the other day that was about 20 years old
around that building were several AC units and when the place was new someone had build little wooded roofs for the AC units and shingled them

over time, the frames of those roofs had come loose and there were several pieces of particle board, with the singles still attached, laying around
i picked them up and put them away, because it looked like someone had used 1 inch nails to attach the shingles to 5/16th sheeting
