I don't know about your neck of the woods but here in Wisconsin if you get caught trapping, fishing, hunting or even gathering wild edible plants illegally the authorities can and do confiscate everything involved... weapons, equipment, vehicles... pretty much everything but the clothes on your back. As many homeless people and transients have learned, the State doesn't much care if everything you own is in your pack. Get convicted (which may take several months during which you won't have access to your pack anyway) and it's the State's, period.

You may want to rethink your idea of living off the land on your journey.
