I haven't camped in an area that requires packing it out. I've been in areas that have discussed it. In those areas they have a hard enough time getting people to follow the current regulations. I felt like the new regulations would just impact the people who are already doing their part and would have no effect on the people who are causing the damage they are trying to stop.

If an area is so impacted by human activity to truly require packing it out I'd rather not spend much time there. It is either too fragile or more likely too crowded.
