Lloyd,
I think you’re onto something. I’ve seen that pattern myself. Another strong pattern I’ve seen is how a sense of community perpetuates hunting. Nuclear families and extended families that hunt and fish tend to perpetuate children that hunt and fish. Sometimes that sense of community goes even beyond family and to a hunting or fishing club or even larger — for example many of us have seen small towns that take pride in the hunting/fishing traditions in their community.

I’ve always thought sense of community was a foremost factor, but I can see the economic angle too. I don’t think these factors are mutually exclusive.
