I've watched some videos of musky fishermen and I can solidly say there are no more dedicated anglers that I have ever seen. They fish tons of hours, some during the night and if they get 1 fish a weekend it's a huge success. If I caught 1 fish for every 20 hours of fishing, I would sell my boat. Now that I think about it, maybe I should not add up the hours and compare that to my punch cards.
Definitely true. My buddy said we are fishing sun up until they close the launch we left out of. Ate lunch on the boat between spots and just kept casting, casting, casting. My forearm and shoulder are still a little tender from it! (damn lures are huge too some of them)
