AFTON – Emergency personnel across the county were kept busy yesterday as freezing sleet and rain – coupled with temperatures that hovered at or near the freezing point – made for treacherous travel on area roadways. All told, units out of Guilford, Greene, Brisben, Preston and Norwich responded to minor accidents throughout the day. In Afton, a woman died after her van struck a tractor trailer on an icy I-88 at approximately 1:43 p.m. near exit 7 in the Town of Afton.
