BANGOR — In January of this year, a U.S.-El Salvador Sister Cities Delegation from the Bangor area met with residents of Carasque, Bangor’s sister city, and with multiple human rights agencies in El Salvador to investigate issues of forced migration. What was learned rearranged the thinking about the nature of the current migration crisis, and might help you see things differently, too. Delegation members Dennis Chinoy, Joan Ellis and Katherine Kates will share what they learned and facilitate conversation to follow 6-7:30 p.m. Thursday, Sept. 13, Bangor Public Library, 145 Harlow St.
