Reflection - stone rubbings

Our exploration last week left me with a few things. First off, charcoal under my fingernails that seemed to never come off!!! What is the trick? Also that stone rubbings appear easier than they are. Alas, it was great to see more of the cemetery. I started to realize what I may want on my memorial. By far the coolest thing for me was the grave marked by a signature. It was interesting to take another kind of look at the monuments by seeking information strictly through the icons.
