Site position for water but we rarely get any rain. The big thing we have encountered while cowboy camping are gnats, mosquitoes and scorpions. There are times we have to cowboy camp to cut enough weight so we can reach an objective with sufficient water but picking up a rock to use as a tarp weight and finding a huge scorpion underneath or being eaten alive by cedar gnats doesn’t make for good sleep. Everything seems to come out in the desert after sunset lol.
