Okay, sorry it took so long for me to respond guys. I've been packing for the Michigan get-together slated for tomorrow night. I typed that post out in the morning and I must have been pretty drowsy because there are plenty of typos in there!
Anyhow, great responses guys and lets keep this discussion going a bit.
Sounds very nice Fonly. My remembering of things is that when your are under age of twenty and have a woman beside you in bed that you never get much sleep anyway

In case you are concerned, that will change when you once you approach fortyish.
Awesome comments 1Tracker; that is exactly the kind of discussion I was hoping this thread would stimulate!
Also many good comments Ravaillac. Now we haven't had a whole pile of hammock posts yet, but I'd like to see somebody chime in.
Still am I the only one deathly afraid of sitting in the middle of nowhere stuck in a bivvy sack. I just have this horrid vision of a bear coming along and enjoying a human fajita. In a tent or a tarp, you are kind of free to move independent of the walls of your surrounding shelter but that bivvy is going to hold onto yeah. Maybe its all just sillyness, how vulnerable do you bivvy folks really feel when you are out there all alone?
