Last winter I put clear vinyl shower curtains around my run to wind and snow proof it but I put a lot of staples in the wood, went through a lot of vinyl and still would end up outside in the dark in a blizzard re-stapling the flapping plastic. I've been looking at plexiglass sheets but that stuff is super expensive so I was resigned to using plastic again until I went to Fleet Farm. They had Optix clear acrylic .080 sheets for about 30% off and they weren't high to begin with. I got 4 36"x72" for $96, 3 30 x 40ish for $42 and 2 24"x30" for $24, total $162 plus $15 for mirror brackets to put them up with. I bet I spent $40 on plastic last winter and these panels should last for many years. Yay Fleet Farm! Also their gas was 3.48 vs 3.89 in my area for premium.
