This week’s Regional Roundup from Rocky Mountain Community Radio includes a look at efforts to commemorate the 140th anniversary of the massacre of Chinese workers in Rock Springs, Wyoming. We head to a rural Colorado gymkhana, where riders of all ages show off their skills. We listen in on an audio postcard capturing the birdsong of a Ponderosa pine woodland near Boulder, and we visit a bustling farmers market in Paonia, Colorado. We round out the show hearing from the author of Food Fight: Misguided Policies, Supply Challenges, and the Impending Struggle to Feed a Hungry World about the challenges ahead for feeding the planet.
