Interesting article... The most telling line from that story, perhaps, is: "Oddly enough, public outcry has been remarkably muted." It's a shame that these growers are not taking good care of the parks where they've set up shop (leaving garbage, etc). Hmm, maybe National Park preservation is just another reason why this country's drug policy, especially regarding marijuana, is so misguided and in need of reform. Were marijuana not prohibited, profit margins would bottom out, and these gun-toting, Park-using drug kingpins would leave the market. Individual people would be free to decide for themselves what they put into their body and could grow or buy it legitimately--and the goods would not have to come from National Park land.
