hi citizen : when i go on trips were i might find myself on a unplanned overnight. i carry a little more than just my survival tin . i carry my suvival pouch with contents which mirror the s.a.s survival book along with 1liter or more of water and maybe some light sleeping gear and extra chow. by the way i find the survival bag is a lot better to sleep in, than wrapping a survival blanket around yourself as you are t-totaly covered in the bag. also if its not raining or the winds not bad i don't waste my time on a overhead shelter i just sleep under the stars <img src="images/graemlins/smile.gif" alt="" />
