The hand of man is everywhere. We were on a beach campsite on Pickerel last year and probably the best tent area had been used as a latrine. Besides the fact that we could see lights on the horizon and my cell phone worked, it wasn't my great wilderness experience that night.
I have no problem with log benches (dead of course) and a fire pit. Bring the rest home. Regardless of what our definition is of "wilderness," this is the real wilderness experience to the vast majority of visitors. It's incumbent on us to keep it in its same relatively pristine condition. Just that alone is going to be really hard to do going forward.
