I saw some serous natural ground blinds this last week end at a ranch were I was dove hunting. They were amazing, they were built with T-post and chicken wire with cedar woven in, they has shoot through mesh they take down while hunting. they were the size of most bedrooms. I've done the pop ups before, but the last five years I've made natural ground blinds. I love em. I'll never buy a pop up again.
Now if you're hunting several places a year I can understand the pop ups, then I would buy a double bull.
