I wouldn't want to see how much it costs in relation to a lb of meat. The experience, stress relief, and relaxation far outweigh the harvest IMO. All the rest is just money I'd spend on something else anyway.
However, if you think hunting is expensive, the cost per lb of fish for an offshore fisherman is much higher. By a lot. Especially when you factor in the boat, insurance, fuel (try an economy of 1.5 to 3.5 mpg), tackle, bait, ice, food etc. LOL, hunting is cheap by comparison unless you travel to exotic locales to do it all the time.
