Let me make clear what I intended to say at 8:30pm so your clear and everyone else.
Anyone who has driven that road knows if you go off that road it will be impossible to be seen from the road.
You would only be found if someone were actually off the side of the road and looking carefully.
And because of that reason - it amazes me that the Highway Patrol did not take that kind of time to investigate a 911 report of a collision. You need to get out of the car and walk the area.
If I know that from driving it a dozen times or so (and for all the people out there that haven't driven it - NC, SC drive is the longest part of the east coast drive and you never forget it) then highway patrol should know that as well.
How do you know that the HP and the EMS didn't do just that?
