I'll say a favorite fly box full of your favorite flies for your
favorite water. Store-bought flies, self-tied flies, friend's flies --
productive flies that you have confidence in, even if you don't know
the names or remember the lineage of most of them.

Anything else can be replaced with a lot of money and a little trouble.

You hear that, Miller? You hear that? You laughed when I did a full
Reid on Penns and watched my fly box float down the river. Ya never
even blinked twice - just watched it go. Never tried to save it. Just
giggled when ya asked me if that (pointing off in the distance) was my
fly box. Remember this, Miller, pay backs are hell!
