Surprise at the invisibility of rock piles - from Sept 2004

"You have to admit that with sites like this right there in Lincoln and sites like the other day near Boxboro center, that there is an overwhelming number of these rock piles sites around here. It is not just an impression, it is true there are rock pile sites in every single woods you look in. Could it possibly be that they are so inconspicuous nobody has noticed them anywhere and that, in fact, they exist in overwhelmingly large numbers everywhere -say- along the eastern seabord? I can't believe that. Over time I have gotten much better at ferreting out these sites. Apparently last time here, I only saw a very small fraction of what was there. So it is probably difficult for most people to notice these sites at all."

Update: sorry about the arrogance.
