Re: Fly in and camp out destinations?
this would be doable flying in to alamosa, co (san luis valley airport) and fishing the conejos river w/about a 20 mile shuttle or hike down the highway to the river. the shuttle could be arranged easily enough.
same goes for taos, new mexico, to fish the rio grande or red river.
albuquerque, nm, has several good fly fishing options and camping within minutes of town and a major airport.
i'd check some northern california options along the sacramento river and so forth.
and look at jackson, wyoming.
