My father is retiring soon and moving from Houston to Durango. He
doesn't fish right now but has expressed an interest in taking some
lessons up there after the move.

As a retirement gift, our family is considering getting him a custom
built fly rod. Unfortunately, we know very little about the area and the
tackle requirements.

What sort of specs should I have in mind for a good quality beginner's
rod for that area?

Thanks,

Mark
