I thought the POD for 7/26 was a real work of art.
I also think being offended by a scrap of toilet paper or a bit of aluminum foil left in the fire-pit borders on OCD behavior; IMO it is far better in the fire-pit than strewn about the campsite. 
I agree with Solus, nails are sometimes useful and you need good eyesight to even notice them most of the time.
Everyone has their own idea of what the "ideal" fire ring is.  If it is too big, YOU have obviously chosen a site which is used a lot. . . and which could easily disappoint you in other ways (above). 
"No sign of human hands..." Really ?!  99.9% of you live in-town (city, megalopolis) surely any woods or green grass is more wild and untouched than city life.
