I wouldn't do anything. Pot ought not be illegal to begin with (if you want to kill yourself, its not the governments business to spend billions each year stopping you) and last I checked the only harm pot heads ever did was listen to bad music and drive to slow (well, I guess electing Nancy Pelosi ought to count too).

I wouldnt hunt there anymore, or at least scout there. I suspect that by the time the season really rolls around those folks will have cleaned and harvested things so maybe go back then.
