im going on a four day camping hike/trek in south carolina. i am looking to buy a large alice pack. i need the whole thing, straps, pack and frame do you guys and gals know a website to buy one on? i prefer a used pack like one you would get at an army navy store but all the ones around me dont sell gear like that. and if you know a web site that would give me a solid list of what i should bring that would be great. im sure some of you have been on this kind of trip in the past what did you bring? im going with a friend who does these kind of trips alone so i know there is a few things i wont need that he has, id rather be over prepared than not. and a question about water purification systems. he has a descent one and has never had problems but im not real secure with it. guess im used to bottled water readily available.i have basic camping gear for when the family goes. (we like primitive camping no campers or electricity, mostly at campgrounds). thanks sorry for the long post. we are going at the very beginning of September if that helps. thanks again
