In our family, there was no clear line between religion and flyfishing. We lived at the junction of great trout rivers in western Montana, and our father was a Presbyterian minister and a fly fisherman who tied his own flies and taught others. He told us about Christ's diciples being fishermen, and we were left to assume, as my brother and I did, that all first-class fishermen on the Sea of Galilee were fly fishermen and that John, the favorite, was a dry-fly fisherman.

Why was John assumed to be a dry-fly fisherman?

I think that maybe it's a high honor to be a dry-fly fhiserman.
