Correct me if I'm wrong.

Since all the pictures show the hennessy hammock hanging with the tarp in place, I got the idea it was a one piece setup, with the tarp permanently fastened to the rest of the rig.

The true scoop, as I now see it:
The tarp is a separate piece. The hammock and bug net are one unit. (Like a Byers Mosquito or similar)

LIve and learn. The weather shield thread opened my eyes to the truth. I was sitting here thinking "why would you cover the tarp??" And then it dawned on me!!!
