Everyone should carry some sort of personal mess kit. I carry my stove inside a two-piece aluminum case which breaks down into two small pots. Water Never drink untreated backcountry water. At least every other person should carry some form of water purification. I carry a filter.
Some hikers prefer purification tablets.
Boiling works, but it takes a long time, it uses lots of fuel, and it requires you to wait until the water cools before drinking it. Shelter Trail hardened backpackers often camp under lightweight nylon tarps. The more comfort-loving among us prefer tents. Plan on bringing at least one tent for every two persons. U.C. Outdoors has several tents to lend.
