A curious thing happened this evening, curious to me at least. Maybe everyone else is aware of this phenomenon. I was talking by phone with a friend who lives about ten miles from me, and had a nature program about Niagara Falls on a local PBS station. I had it muted while we talked but was enjoying the pictures. At one point they were showing fireworks over the falls. As it happened, this friend and I were at Niagara Falls on the 4th, some years ago. So I told her about the fireworks on TV. She turned on her TV while we talked. On my TV the fireworks were over and they had moved on to a winter scene. But when her picture came on it was the fireworks. I was surprised because I didn't know there could be that delay between two televisions only ten miles apart. When I commented on it, she told me of another time when she and her son were watching the same football game on different TVs in different parts of the house when she started cheering about the winning goal before he had even seen it on his TV in the same house. I'm sure there must be some perfectly reasonable explanation for this but I don't know what it is. Maybe some kindly EE can explain it to me.
