What a terrible thing to happen!  I met those busses seconds before this happened.  That area of roadway is the site of many serious accidents in the past.  It occurred just north of 2 very tight curves, separated by several narrow bridges.  I must say that they made a sight, large, new shiny black busses travelling in extremely tight formation.  I can believe that they connected as closely as they followed one another.  I am so glad that the injuies are not severe and hope they are able to continue on their trip as planned.  People tailgate all the time not taking necessary stopping distances into consideration.  Please, ya'll, be careful, drive safe.  We have an enormous deer population down here and they are on the move right now with all the hunters in the woods and they aren't mindful of you and your vehicle.
