CARTHAGE, N.C. (AP) — Tens of thousands of people are bracing for days without electricity in a North Carolina county where authorities say two power substations were shot up by one or more people with apparent criminal intent. Across Moore County southwest of Raleigh, businesses handed out free food or coffee and and often conducted transactions in cash. The county announced that schools would be closed for a second day Tuesday due to the lingering outages. Traffic lights were out around the county. Drivers treated intersections as four-way stops, which caused some traffic in places such as downtown Carthage.
