By DENNIS WYATT 209 Living MORGAN HILL — Shangri-La does exist. It’s a roughly two-hour drive from the Central Valley followed by a blissful five-mile hike to a spot that in another day and age one might aptly have called a swimming hole. Once there you can reward yourself with a lazy nap, stretched out on a boulder at the edge of a 20-foot wide and 8-foot deep pool of clear water on Coyote Creek fed by early spring runoff.
