Many of us have a favorite personal place in nature where we find refuge. Typically it’s a place where an elixir of rock, water, air and woodland soothe our spirits. Come hear how writing “The Guide to Walden Pond” helped Professor Robert Thorson better understand Henry D. Thoreau and how this understanding can enrich your own space and experience. The author will answer questions and be available to sign copies of his seven books. His most recent, “The Guide to Walden Pond” (Houghton, Mifflin, Harcourt) will be published in March, 2018 as a contribution to the year-long bicentennial celebration of Thoreau’s birth. Audubon Environmental Education Center, 1401 Hope Street, Bristol, RI; Fee: $10/member; $14/non-member. Ages: Adult. Register online through the events calendar at www.asri.org.
