Attention, Verizon customers: Would you like to get better cell reception in Chilmark and Aquinnah? If so, Chilmark executive secretary Tim Carroll is urging you to write to Verizon Wireless representatives, asking why the company won't join the newly operational Distributed Antenna System (DAS), which will greatly improve wireless service for certain carriers in the area. AT&T has elected to participate; Verizon has not.
