& in conjunction with using bags to carry water,especially the 1 gal.ziploks if you are toting more than a few,I have found that,the cheapy laundry bags from the dollar stores,do a real good job of carrying 5-1gal ziploks(aprox.4+ gals. of water)up to a campsite 300yds away,the laundry bags pack small/light,& can be used for cushioning purposes when filled with leaves,etc.or whatever else one can think of!
