Southernson - thank you for taking the time to report this to the Ranger District, we all hope they catch whoever it is. Forest Service law enforcement, like most I suspect, is stretched thin. They would all like to catch every offender selfishly disregarding public land laws, but they have to prioritize given the limited resources they have.
For anybody witnessing violations, please take the time to report it to the land management agency AND the game warden. Be sure to include pictures and precise location info, GPS coordinates are best. Even if they can't put any time into it then, they will likely document it. And then if similar reports come, it will be useful. We have to at least do our part and report what we see out there.
