I thought, depending on the location, you could lay on the ground for a power nap. while using what kit you have as ground sheets (news papers, magazines, clothing) and as a result of this you could be waking up cold, achy- slower, unhappy. waking up with some aches and pains, cold and miserable after an unexpected night out is better than dying trying to find a bed. also, it would be cool to improvise the garbage bag into a top to help keep you dry when raining- seen homeless people do it for years. negatives for this could be more noise when moving, slower weapon/item change due to the over layer. if this has been covered, my apologies -I'm new to this stuff
