The Big Island has a lot of head on type accidents.  Not sure why this is the case but it has been 
very common over many years whether on the Hamakua highway or the Saddle Road.
I still remember seeing a very, very close call on the Hamakua highway near Honokaa, some
years ago when I was still in high school.  The driver of one vehicle was a woman and I vividly remember
seeing her seemingly frozen at the wheel, eyes wide open seemingly not knowing what to do at
the approaching vehicle coming toward her head on.  Had the cars collided at the speed they were
traveling, it would have been fatal for both drivers.
