Sweet Briar College yesterday investigated a photo taken of what looked to be an alligator on campus… Evan Jones has the details.   No one will confuse Sweet Briar College with the everglades, but a college e-mail to staff and students yesterday says there have been two reports of a possible alligator sighting in the upper lake on campus. Evan Jones, WLNI News— Within a few hours of the school’s announcement, a Wildlife Biologist with the game department reviewed a photo taken of the alleged beast that looked to be about 6-feet long. According to the scientist, Central Virginia simply is not healthy for an alligator…and concluded that it is most likely a log in the water.
