I'm a long time lurker, but that's another thread. Anyway where does one find a pack frame. I haven't seen any on net sites or in outdoor stores. What I am thinking of is just something you can tie or fasten things to that has a reasonable or good suspension. Do a good bit of trail maintenance and tieing mattocks, rakes, etc to my day pack has torn up the daypack. In addition it is a drag to carry these implements of destruction for several miles before you get where you are going.
