In this episode of Think Radio, Gunnison Country Times Publisher Alan Wartes talks with retiring Gunnison County Public Works Director Marlene Crosby. After 37 years overseeing everything to do with county roads, bridges and utilities, Crosby is stepping down. The conversation covers a lot of ground — from ways in which technology has shaped the job in four decades to what it has been like to be among the first women to take a leadership role in the profession.
