Although you can't tell because of the snow squalls and sub-freezing temperatures, we are quickly approaching spring in Northwestern Pennsylvania. And with the anticipation of warmer weather, birds chirping and leaves returning to trees, many of us hit the books to recall the words of our favorite nature poets. Dr. Bob Hass, from Edinboro University's English & Philosophy Department, joins us today to discuss his lifelong quest to understand Robert Frost, his penchant for living outdoors and writing about it, and his predictions for the future of poetry. Hass is the author of "Going by Contraries: Robert Frost’s Conflict with Science" and the poetry collection, "Counting Thunder". He is currently co-editing "The Letters of Robert Frost" with Edinboro colleague Donald Sheehy for Harvard University Press.
