Brenett, Kim, Lucretia, and Omney belong to Montana's Crow Nation. They love their reservation, but there aren't enough houses. They wanted to find a cheap way to build durable homes. There's straw all over the place, so they did some experiments to see if straw bales could be used to build a house. In this video from DragonflyTV, they test straw, stucco, and cinder blocks to find the most economical and durable building material.
