RE: What would you do?
If concelment is the issue why not carry a shotgun? It would be a better choice for the wife if she has to use it. Personally I think the fears are unfounded. If you are worried about backwoods pot plots the best bet is to steer way clear if you see one, they are probably booby-trapped, but not watched 24/7, it would expose the criminals to being caught if they were always at their fields. Other than that I doubt there's any nasty human critters out there. As far as animal critters; your bow should be enough for most situations while hunting, you could leave a shotgun in the camp with the wife in case of some need (rabid fox or coon or whatever). That should cover the bases nice enough.
