As I mentioned to you earlier, I've yet again nagged Parks about it. Even if they do nothing, at least they see us as concerned about the environment. At best, they will hopefully step up patrols in the area, although they have their hands full deploying personnel to cope with the surge in violent crime in the Park (which is, admittedly, more important) around TM.
Just to reiterate Greg's call, please just ditch any firewood you find there, and bounce any rifraff you see. The worst trash I want to encounter when climbing at a crag is lowlife climbers, anyway :-)
