i can't say i have had a horrible experience that made me utterly miserable when nature called. i have seen regular cleaning done while walking by and waiting. That picture on the previous page is just luck of the draw (good or bad luck? guess perspective determines that).
i took an odd picture in one of the porta potties outside the entrance in 2004 (maybe someone with the same artistic motiff from the Pic-Asso responsible for the material for the picture on page one): it was a used feminine device in the green plastic urinal (looks like a big slab of bacon with a string attached). How it made it in there is anybody's guess. i would post the picture here, but i just can't bring myself to put it on the internets for url purposes.
