Following the cigarette-butt controversy, the Paulsens had installed a high fence and planted a line of ornamental spruces that had since grown up enough to screen them from the spectacle.
The border among the pines and spruces and wild flowers is just marked by a yellow sign warning against trespassers, and a long pole that has been slung across an imaginary path.
The job of the new center, to be called the National Center for Advancing Translational Sciences, is akin to that of a home seller who spruces up properties to attract buyers in a down market.
