A large triangle hovering over Bluffton, SC near Buckwalter Road.We do not know what we saw. We stopped for a light, and I asked my husband, did he see it. It was so large, that he had missed the lights that showed it's shape. A very large triangle. Two white lights blinking on top, two white lights blinking on the bottom, and to the midpoint on our left - a flashing red light. I exclamed it was as large as a football field, my husband believed it was larger than that. It wasn't tower lights, it was low to the Earth, and hovering, like on a side - not flat across. When the light changed we continued on our way, wondering what we had just witnessed.
