It should be possibly a relatively easy task to go through it this year. I might even kick some things out as not needed.
Note to self: This is the year to make a decision about fishing equipment (a rod and lures in the book shelf does not fish it self even if you live overlooking a water.) Use it or loose it.
Although not sleeping out (still to cold for that) all the light weight hiking gear and clothes will be needed for our week of rummaging through the countryside and historical places.
