Ten years ago, Darren and Espri Bender-Beauregard of Paoli built a straw-bale house on 12 acres of land in Paoli, Indiana. With their increased concern of the direction the world is headed, as a whole, and what kind of future that may bring, the couple and their three children — Viola, 9, and twins Eleanor and Sylvia, 6 — have built a life focused on homesteading, self-sufficiency and sustainability.
