The upper Sky, shhhhh...... or it will be overun with fly flingers and feather throwers.
Actually I'm glad to hear you discovered its secret, wild summer runs. The fishing gets better as you get into September and October. It is a gem of a river to fish. Although the last few years I've noticed there are more gear and spin fishers present, I've had the same experience as you with very cordial and courteous fishers regardless of the types of equipment being used.
