Several of the participants in this weekend’s “Crop Walk” in Janesville have been involved in each of the event’s 40-years. ECHO Associate Director Jessica Lochker calls their involvement invaluable. Lochker says $45 thousand were collected last year. More than 200 walkers from 15 churches are expected. The walk is set for 1:00 p.m. this Sunday at Cargill Untied Methodist Church in Janesville.
