I'm currently reading various sections of the excellent Bill Thorness book "Cycling The Pacific Coast".
I note that he mentions in it that his route differs slightly from the ACA Route (Which I'm using on my GPS) in that his route is the "safest and most scenic route, including use of push bike paths where appropriate".
With this in mind I've been going over the ACA route in Komoot and have made a few small changes to his route already.

My question is this- would you guys recommend I changes most of the ACA sections where they differ from his or it's just 6 and 2 3's?

There's some milage to be shaved off in some cases:
In one part he entirely bypasses Anacortes in Washington State- is that town worth seeing etc or..?

As someone who's entirely unfamiliar with this route and area I'd love to hear any thoughts if anyone's in the know..!
As always- nae bother if not; I've already more or less got the route down, and now I'm just enjoying tweaking it here and there as I count down the days.
