Round orb or ball of bright white light seen at Johnson Square in Savannah, GAMy two sons, my daughter and sister were at Johnson square in Savannah, getting ready to take a ghost tour around 9:15pm, when my youngest son of 8 years of age, and myself saw a very bright white ball or round orb come down across the clock tower from left to right on a 40 degree angle. We could not see where it originated or where it went because of building on the right and left side of the clock tower there.
