Destination Highways WA & BCBe sure to check out the site, even if you have no plans to visit WA/BC, they have videos of many of the rated roads.
If you live in or near Washington State or British Columbia, these books are FANTASTIC! They rate the best m/c roads in the state/province, give detailed descriptionsof the route and how to get there, maps that'll fit any tank bag with a map window (though I'd photocopy them rather than rip them out of the spiral bound books) as well as listing most of the m/c shops, gas stations, eateries, hotels/motels and campgrounds.
Here's a sample of how they rate a road:
The above example is one of my favorites, North Cascades Highway. Apparently, they like it too as they rated it as the #1 road in the state (DH1).
I've been dropping heavy hints for these two books for Christmas or Birthday gifts. Never happened, so on my birthday this year, I bought them as my present to me.
