Is it private land like
>>2841704 and
>>2841720 said? OP, it sounds like you're getting upset about what people do on their own private land.
They are right to protect it from litter. There is a private ranch that I have hunted elk, antelope, and deer on. The ranch is open and easily accessible. Anyone can drive onto the land and drive around. For the first time ever, the owner was thinking about closing it off, due to the trash accumulating everywhere. The last time I was there, I took a large black trash bag and walked down a random road leading out of my camp site. I grabbed every beer can and bottle I saw. I hadn't walked for more than 20 minutes before I filled the bag.
If the people in your lazy, low quality picture, are truly the owners and they still want to keep the land open and accessible despite people trashing it, and they have figured out an okay solution to prevent litter, then good for them.
