When camping out in the wilderness, it is easy to bring too much. In considering what to leave behind, give a thought to forgetting the tent. By bringing a stout sleeping bag (Coleman offers some very nice affordable bags) and a large tarp, you are sure to stay dry and warm.
The tarp should be big enough to wrap under the sleeping bag to act as a moisture barrier with the ground, and also on top to prevent rain and dew from wetting you from above. It should be long enough to tuck under your feet and keep the wind out, and tuck over your head if you wanted to shield yourself from the wind and weather (be careful to leave a ventilation hole: don’t tuck yourself in too tight).
Veteran campers will acknowledge that on a clear night, bagging is better than tenting, and only under severe conditions will a tent be preferred to the convenience and pleasure of the raw natural experience of bagging.
