From Random Acts of Kindness: "The building sat over the banks of the lake within a stand of yellow birch. The coiling twig work gave the pillars the look of sun-bleached trees. It had an elfish look, a Thai-temple look. Now she slipped off her sandals and pressed her palms together. With the boards hot under her feet she walked with attention, seeking calm in Buddhist walking meditation." Boathouse at Camp Topridge in the Adirondacks.
