All the land they mentioned in this piece with either State or National Parks, both of which forbid guns and dogs, the best two things you can take with you into the outdoors. I say, leave 'em for the guerilla farmers, I'm not going there.
The worries about environmental damage are overblown. If that is their definition, then all the farmland in the Central Valley is environmentally damaged. Jeez. Just take out the trash and the forest will be back in a few years.
And for the guy who said the Feds should sell National Forests because the Constitution doesn't authorize them to hold land, I say hey, where else can people who aren't great land owners go out and practice shooting in a more realistic environment than a controlled range? The Feds'd be violating my 2nd Amendmend rights if they sold off the National Forests or BLM land!
I wonder if the fact that this stuff tends to occur on land where dogs and guns aren't allowed is coincidence or not. I sometimes wonder if I might run into some of these guys while out in National Forest/BLM land one day.
Also, I don't know how common this is, but in rural areas of California, it isn't unusual for people to take time off from work in the fall to harvest weed. I'm not talking about illegals, but more backwoods type people.
