My father was a hunter, angler and backpacker and we enjoyed lots of quality time together doing those things, and I still do all three as much as time will allow.

I recommend getting a longer takedown rod, something 5 or 6 feet anyway. Years ago ultra-light spin fishing was very popular but lost favor among serious anglers who release most of their catch because playing a fish too long increases stress induced mortality. For smaller fish often found in backcountry, light gear is fine. I tried 2 lb line and found I lost too many fish and lures and went to 4 lb.

Tenkara fly fishing has become popular but it is not as versatile as a traditionsl fly rig.

Good luck and have fun.
