We saw a strange sight a few nights ago- and we've seen this a couple of other times over the past year. At nighttime, we noticed many lighted objects- a kind of warm glow, floating and seemingly drifting with the wind across the sky. There were perhaps 20 or so, gently floating in the sky. No flashing lights, just bright glowing light. The location is coastal South Carolina near Charleston. Anybody know what this could be?
