i remember reading bits of a book from a guy who was a park ranger and who championed the idea of getting rid of all roads and car traffic into the parks. i wish i could remember his name and the book title, i think u would truly enjoy it. i shall poke around & see what i can find.edging ever deeper into the green of the park, away from asphalt & steel, under a redwood with gently creaking boughs, closing eyes; the sound of traffic becomes the sound of a mirthful stream...
