Matt Reeves, Montpelier’s Director of Archaeology & Landscape Restoration, tells us how he is using a new technology, Light Detection And Ranging, or LIDAR, to peer beneath the forest canopy and find traces of the past that have been hidden for centuries.

After we finish with Matt, we’ll talk about a controversy over California’s ban on small, “battery” cages for chickens, and how that ban affects interstate commerce -- and how Congress may soon respond. Our guests are Dave Duquette, the National Strategic Planner for Protect the Harvest, and Bob Martin, the Director of Food System Policy at the Johns Hopkins Center for a Livable Future.
