A correspondent is working on a project which profiles sites around
the country where ideals, history and aspirations have been made
permanent by being engraved in stone.  Does anyone know of any
sites around the world where Twain's words are carved in stone?
The Hartford House with the new Vistors' Center comes to mind.
Are there others -- memorials, statues, public libraries,
government offices, theaters, landmarks, schools, etc. ?
