Arkansas - September and October hoppers and streamers against the banks. With no Gen you can wade, with generation it is drift or jet boat only. Big Browns and stocker bows. I am going with some folks September 2-6th.
I'll be in the Conejos, CO drainage in a few weeks and report back. They need some water pretty badly.
Backpacking and camping..... Yellowstone comes to mind. Also the Gunnison drainage in CO. Taylor River, Gunnison, East, Sprign creek, Lake Fork Gunnison, Cebolla Creek, etc. I am sure you could spend an entire summer and only see 10% of it. If you want to float - do the Black Canyon or Gunni Gorge float. Totally wild and scenic for big fish.
