Pop-ups are great and we use them for some of our clients. If they are used for deer season, and the weather gets cold, ice n snow, I recommend taking them down. They cannot withstand the torture of being unzipped with Ice on the zippers and will tear up. I also have built quite a few wooden blinds for them to hunt from. Just a 4x4x6 with a 14" window all around, place camo burap available from Walmart, to cover the windows. Make slits in it various spots to shoot through. Cost roughly $150 to make one and they will last for years and it can be left in place, if you are hunting on private land.
