Fishing is such a hobby which is associated with QRP in many ways.
First ,if you are bored calling stations with one watt and poor antenna with no answer, you can relax going fishing.
Second , you can use your rod and spinning wheel to install 1/2 wave wire much easier than climbing a tree.
Third, it's good for your fitness and health.
The biggest fish ever - 15kg salmon Tasty pike caught on the lakes during 2002 QRP trip.
