Got several backpacks out of the storage room and went through them. The issue with having a collection of packs is the gear gets spread through them. Depending on the length of the hike, and what I am doing, certain gear may be brought along. After awhile, gear is spread through all the packs. There might be a stove here and a stove there, and a knife here and a knife there.
Things get so disorganized the packs have to be pulled out, emptied, and everything rounded up.
For example, I have been using the Sawyer PointOne on a couple of outages. However, I still like to bring the Katadyn Vario from time to time. This means the Sawyer Pointone is in one pack, and the Katadyn Vario is in another pack. The problem starts when I forget which filter is in which pack. then I have to go digging through the packs until I find the gear I am looking for.
