Fall is a great time to be out on the rivers. The weather is great, the colors are awesome, and fish start to really feed again to put on weight for the winter and the spawns.
Many people forget that in the Fall months rivers start to see increases in bug numbers as the water cools. Watch for blue wing olives, mahogany duns, tricos and several other noteworthy hatches. By this time of year fish are used to seeing terrestrials like hoppers, ants, and beetles so these patterns make great options between hatches.
Don't forget to pack your streamer box as well. Brown trout seem to get especially vicious just before the spawn and streamer fishing can be great. Less people, hungry fish, fall colors, and fast fishing - what's not to like about that?
