A few years ago the library where I work produced a bibliography of
"Porching" books. Many of the books have porches or porch chairs on the cover, but others were chosen because they are suitable for reading on your porch....while you are waiting for passers-by. If you are porch deprived, I suppose you can read them on your deck, in your garage, or from the peak of your roof.
