Randy Olson presentations begin Tuesday

A three-day series of presentations by scientist and filmmaker Randy Olson begin on Tuesday Sept. 21. One highlight will be a 7 p.m. Wednesday Collins Center for the Arts screening of Olson’s film “Salt of the Earth.”  That film, which premiered 20 years ago, features Stonington brothers Brian and Stevie Robbins describing life working in the lobstering industry.  The Robbins brothers will be present Wednesday to engage with Olson in a post-film discussion.  This is the only event on Olson’s itinerary that requires a ticket purchase.
