after reading about drr324's story about almost spending the night in the woods, because he forgot his daypack. it got me thinkin about it and i was wondering if any of you have ever "had" to spend the night in the woods for reasons unforseen. and what did you do about you situation?
a friend of mine shot a "phenomenal" buck a few years back and spent the entire night in the woods tracking him. he did stop and build a fire to dry himself by, but then continued tracking.
i believe he spent somthing like 18 or 19 hours straight in the woods following that deer, and he never did find it.

10 years ago I had to spend the night in a swamp, wasnt fun. got turned around tracking a hog that was gut shot. Ended up about 5 miles away from my camp. but it wasnt till morning that I got my bearings back and was able to find my way out. Spent the night next to an old oak tree, just me and my hog  

Those Tyvek painters suits make a very light to carry but effective overnighter.  Just like goretex in properties.  I have an XL to fit over everything I have on-except pack and bow.  Bugs and water-off you, retains some heat.  weighs next to nothing-cheap insurance.

Roadkill, that's a good suggestion on the Tyvek.

I spent all night in the woods out near Abilene, ended up 7 miles from camp as the crow flies. I finally found someone on a road about 5:30 in the morning, I started tracking that hog @ 9:00pm. Bought a GPS the next week.

Roadkill to add to your idea with the Tyvek I vacum packed mine so it is smaller and waterproof till needed.Kip
