By the way, just to be clear, I didn't mean to start a "pot should be legalized" thread, and I'll keep my opinions on that matter to myself. (I prefer a nice glass of pinot noir.)

The point was that organized criminals with automatic weapons are in national parks in numbers never seen before. Sure, there have been moonshiners, meth labs, and God knows what else, but pot farms like this take up massive amounts of land. They are far easier to come across inadvertently than most of the undesirable human activities you'd want to avoid in the woods.
