In Oregon, there have been many, many, many grow sites found by the government, forestry dept and etc, in the forest and on federal land such as parks and mountain areas. Quite an elaborate set up that many cartel members would set up and grow, claim the territory and god forbid a stranger out for a stroll or hike happened by "their" site.
Since they have made marijuana legal here this isn't happening so much as people breaking in and stealing legal grow operations.
