I was fine with the logging trucks when I rode there. You hear them coming, so I just stopped and got out of the way, then gave them a friendly wave as they went by. Always got a friendly response.

It's their road, but if you're using it respectfully they don't mind you being there. And they'll tell the other drivers that there's a crazy guy on a bike out there, so they are all aware that you're there, and also how you're conducting yourself on the road. I found that the vast majority of drivers would slow right down as they passed me to cut down on the amount of dust kicked up in my face.
