I have wondered the same thing, one thing i have been considering is getting the sumnit enclosure, then getting some additional material to sew on and "shred" to give it a "leafy" appearance.

i think the snow camo would make a good pattern once the leaves are off, I also thought about tryign to find Predator camo by the yard then covering the summit blind with it or just having my wife sew me a cover with the Predator.
