Paully, you don't strike me as someone who wants to punish the company or Costco. But the warranty was for winds of 75 mph. Did your gusts exceed that? Only you would know that.
I see you building that greenhouse stronger! You will re-use the panels with a better, stronger frame. It's all about the bones! It has been mentioned here that wood framework stands up better than metal.
I, along with everyone else here, feel so sad that this happened to you.
But you did state that you can't fight Mother Nature, and this is true. For those in high fire zones, earthquake zones, hurricane zones, flood zones, not much you can do. Rebuild.
I look at your horrible destruction, but I see beyond. OMG! Your figs do need protection from that huge snow covered mountain! It has to be bbbbbbbrrrrrrrrr cold there!
Keep us posted!
