SO far I have lost half my mechanical and all my erasers. Bring bunches of cheap mechanical pencils (0.5 mm) and lots of erasers. When I get back to town or Pocatello, I'm picking up a big pack of cheap pencils. Next tip, only put a few pieces of lead in each one. Inevitable, the pencil you lose will be the one with the most lead in it.
The Write-in-the-Rain notebook pouches kind of suck. They are too tight to get the notebook in easily. One guy here used a army surplus water canteen bag for his. I think I am going to borrow that idea. Hammer loops...the fancy ones they sell in the museum store that are all leather and snap suck too. They seem cheesy.
