Henry David Thoreau

On Henry David Thoreau

In the 1840s Henry David Thoreau swapped his busy schedule in Concord, Massachusetts, for a wooden hut he built himself near Walden Pond. We had the privilege to visit Walden in July 2012; it exceeded expectations in its tranquility and beauty - and the swim in the pond itself was unforgettable.
