99 and I-5

are the best two roads probably in the world for showing how many bad drivers are in this world. I'm in-between the two.

When the fog hits... or a dust storm... it's just a matter of time until the news reports a pile-up on one or the other or both.

Like you I have driven both in the fog... and dust... and it's incredible to me how little people slow down. You get stuck in a no win situation... if you slow you're sure to be hit... if you keep up with traffic then the pile up is coming. - JamesJM
