RE: covering a ground blind
Kidd, I use a similar blind. Just keep it down wind of where the hogs are coming thru and don't set it directly in their path. Set it amongst the bushes that are already there and you shouldn't have to worry about covering it. I'll bet the hogs won't even act like they see it. Just so they don't smell you is the main thing, or, hear you fumbling around inside it.
My blind works great for turkey hunting. The turkeys will walk right up to it and past it like it isn't even there! Now deer, they'll look at it and walk around it, they do see it but it doesn't seem to spook them.
