There has been quite a few discussions on this topic. If you could search the archives
a bit using the search engine
after my signature you might come across a few threads. Basically my take on it (I haven't done it) is the best way is to come across to Hawaii
and then head
north. I've done the Hawaii
sail but not the Mexico
to Hawaii portion.
You'll find other opinions I'm certain. Try search titles San Francisco
to Washington or something to that effect.
