That's the problem with a ISP report that people who have never been to the area could not understand. It's a two hill/grade. They had just topped the first grade with about 1/4 mile on a downhill Hill grade to the much longer whitebird grade. There were a couple things left out of the report but it doesn't matter much now even though they're were decending down the first grade when it happened.
I could explain until my face turned blue and know one would understand because they have never been to this particular area famous for wrecks, especially in the winter as I couldn't possibly understand a wreck say in Florida. Never been there!
