We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I remember reading articles on IM Pei and Le Corbusier and that whole crew, and feeling like the crudest sort of countrified dunce, because I just could not figure out the sense of awe they seemed to inspire in the writers covering them. They were approached as demi-gods by such as Life Magazine, and all the slicks, not to mention the newspapers.
RE: "So why has the city's Historic Preservation Review Board unanimously declared the Third Church of Christ, Scientist to be an official D.C.landmark, preventing not only its demolition, but even its unauthorized alteration?"
Because they can.
Knew one board member who worked on heritage paint colors. Boards quite happily drive people nuts with lots of requirements on what colors a house or business has to be.
Many people think that 'raw' concrete is water or damp proof. It is not. It usually should be sealed. Sealers can cause their own problems though. There are so many different kinds (oil based, water based, acrylic, urethane, blah, blah, blah ) and moisture problems and effervescence can occur. Worst case scenario IMO....sealer can fail and bubble and peel off. Will most often use a wax sealer on colored or 'patina' stained floors. Concrete has been stained and waxed since Roman times and the wax never fails. Also tell folks to call back in a few years if it looks time for a new coat of sealer as it should be maintained. Almost no one does. People usually do not maintain concrete.
