What mntrunner260 says. I didn't appreciate the importance of not camping where you hunt when I was young. I now generally stick with the ORP (objective rally point). guidance of the Army, one terrain feature or out of range of direct fire weapons from your objective (hunt area). Water concerns are not a factor in my area. I carry 2 liters on my pack during the hunt. I can fill up to and from my hunting area. If you can't make it through the night with 2 liters, you need to re-evaluate your water usage in camp. I'm only in camp to eat supper and sleep. Everything else except washing my socks and balls is done in my hunting area.
I always tuck my camp in a pocket off the natural line of drift, but close enough to find it if I have a head lamp failure.
I was recently reminded of how all these points come together last archery season. I saw a camp set up right by some water just above a bedding area with a 6 point. Of course the elk blew out, but when I passed that area on my way over the ridge to my camp after sunset, I would let out some bugles to keep those hunters interested in the area they blew out.
