Stonehenge
This is what Im talking about:
>Quick on the draw:
"In July 1996, a 915 feet spiral of 151 circles appeared in full view of the busy A303 road, opposite England's ancient monument Stonehenge, Wiltshire, within a 45 minute period one Sunday afternoon. A pilot, gamekeeper and security guard confirmed it had not been there before 5.30pm - yet shortly after 6.00pm, the massive formation was being spotted by passing tourists. Much smaller man-made designs have taken several hours to complete. This also disproves the myth that all crop circles appear by night. "
Explain this, will you? It's not your friends making themselves invisible during daylight hours next to a busy road and putting down over 150 circles in about thirty minutes, is it?
