Living in a trailer has allowed me to cut down on stuff. The trailer is
small so if something comes in something has to go out. This usually works
but every time I go by storage I am dropping stuff off and picking up some
things. Usually more is dropped off.
I have in the past when I was backpacking, I marked everything with a grease
pencil. Every time I used I wiped off half the mark. Upon return I would
look at the marks to see if it could be left behind the next time.
