X2 about all the great ideas above. Oatmeal, pasta, rice, are lightweight foods to carry. There is one thing I found out on the Katy. Some of the water spigots at the trailheads don't work this early in the season. Also some of the bathrooms are locked.

A couple of changes I made that helped: small [B]stainless steel[B] cookpot replaced my porous aluminum cookpot (found at a thrift store), and a website I ran accross that I really like:
