In this podcast we hear from family and far flung friends (in Norway and Virginia) and explore the traditions, rituals and science behind winter time and solstice. Rachel reads from Jean Ritchie's "Singing Family of the Cumberlands" about old Christmas and the first Christmas trees to come into the mountains in the 1930's. Plus, talk of New Grange, the physics of light, and other lore.  Air Date: December 24, 2017 on KSCO radio station AM1080
