It's easy. You can't leave anything there legally, and you can't take anything out except what is allowed to be removed. You can't damage anything. If you want to leave a stand or camera it's at your own risk. You have no legal rites if they turn up missing. As far as the law is concerned the taker was just cleaning up litter left behind by somelaw breaker and they could findthe violatorand fine the person to boot.

Just voicing the way it is and mean nothing personally. Take your chances.
