Hi Greenlight82 !

I did the Pacific Coast from Vancouver - San Diego in 2009.
I agree with the previous advices
- Wind north to South
- Better views of the ocean when riding north to south
- In some areas, if there was not enough space (or money ) available for a shoulder on both sides of the road, then the southbound side is the one which has the shoulder.
I liked so much my ride of the Pacific Coast that I will do it once more !

With a friend, from may to june 2014, I will do the Pacific Coast.
So, maybe, see you !
