Why can't you? You can with a fish. Just asking. Try asking someone if you can go with them and just sit with them. No offense my girlfriend was the same way until I took her squirrel hunting and all she wants to do is go squirrel hunting and shoot squirrels. Now I am trying to work her up to deer. Trust me you don't think about the whole killing aspect. You are being provided this lovely animal that god creator to feed you family.
But yes it seems expense but take the time a hunter puts in, gas, the way he harvest the animal, gear, man hours and if will probably average about the same price. We just don't see it as easily as that because it is spread throughout the whole season.
