I received a call at around 6:39 pm  from 276-200-4709, this site says it came from Danville, VA about 175 miles from here, and I know no one in Danville.  I answered but no one responded. I could tell there was someone on the other end, they just never said anything.   I said hello a few times then they hung up.

At about 6:47 pm the phone rang again, this time the caller I.D. showed 336-306-8775.  This site says it's a Greensboro, High Point, Kernersville area number.  I don't know anyone there either.  This time I let the phone ring, but they left no message.

Danville, VA and Greensboro, NC are only about 45 miles apart, so the calls are likely related.
